libusb 1.0 Windows binary snapshot - README
*********************************************************************
* The latest version of this snapshot can always be downloaded at: *
* https://sourceforge.net/projects/libusb/files/ *
*********************************************************************
o Visual Studio:
- Open existing or create a new project for your application
- Copy libusb.h, from the include\libusb-1.0\ directory, into your project and
make sure that the location where the file reside appears in the 'Additional
Include Directories' section (Configuration Properties -> C/C++ -> General).
- Copy the relevant .lib file from MS32\ or MS64\ and add 'libusb-1.0.lib' to
your 'Additional Dependencies' (Configuration Properties -> Linker -> Input)
Also make sure that the directory where libusb-1.0.lib resides is added to
'Additional Library Directories' (Configuration Properties -> Linker
-> General)
- If you use the static version of the libusb library, make sure that
'Runtime Library' is set to 'Multi-threaded DLL (/MD)' (Configuration
Properties -> C/C++ -> Code Generation).
NB: If your application requires /MT (Multi-threaded/libCMT), you need to
recompile a static libusb 1.0 library from source.
- Compile and run your application. If you use the DLL version of libusb-1.0,
remember that you need to have a copy of the DLL either in the runtime
directory or in system32
o WDK/DDK:
- The following is an example of a sources files that you can use to compile
a libusb 1.0 based console application. In this sample ..\libusb\ is the
directory where you would have copied libusb.h as well as the relevant
libusb-1.0.lib
TARGETNAME=your_app
TARGETTYPE=PROGRAM
USE_MSVCRT=1
UMTYPE=console
INCLUDES=..\libusb;$(DDK_INC_PATH)
TARGETLIBS=..\libusb\libusb-1.0.lib
SOURCES=your_app.c
- Note that if you plan to use libCMT instead of MSVCRT (USE_LIBCMT=1 instead
of USE_MSVCRT=1), you will need to recompile libusb to use libCMT. This can
easily be achieved, in the DDK environment, by running 'ddk_build /MT'
o MinGW/cygwin
- Copy libusb.h, from include/libusb-1.0/ to your default include directory,
and copy the MinGW32/ or MinGW64/ .a files to your default library directory.
Or, if you don't want to use the default locations, make sure that you feed
the relevant -I and -L options to the compiler.
- Add the '-lusb-1.0' linker option when compiling.
o Additional information:
- The libusb 1.0 API documentation can be accessed at:
http://api.libusb.info
- For some libusb samples (including source), please have a look in examples/
- For additional information on the libusb 1.0 Windows backend please visit:
http://windows.libusb.info
- The MinGW and MS generated DLLs are fully interchangeable, provided that you
use the import libs provided or generate one from the .def also provided.
- If you find any issue, please visit http://libusb.info/ and check the
Support section

- Compile and run your application. If you use the DLL version of libusb-1.0,
remember that you need to have a copy of the DLL either in the runtime
directory or in system32
o Additional information:
- The libusb 1.0 API documentation can be accessed at:
http://api.libusb.info
- For some libusb samples (including source), please have a look in examples/
- For additional information on the libusb 1.0 Windows backend please visit:
http://windows.libusb.info
- It is necessary to install the CE USB Kernel Wrapper driver for libusb to
function on a device. This is obtainable from:
https://github.com/RealVNC/CEUSBKWrapper
- If you find any issue, please visit http://libusb.info/ and check the

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

APPENDIX A - How to maintain code compatibility with versions of libusb and
libusb that use MaxPower:
If you must to maintain compatibility with versions of the library that aren't
using the bMaxPower attribute in struct libusb_config_descriptor, the
recommended way is to use the new LIBUSB_API_VERSION macro with an #ifdef.
For instance, if your code was written as follows:
if (dev->config[0].MaxPower < 250)
Then you should modify it to have:
#if defined(LIBUSB_API_VERSION) && (LIBUSB_API_VERSION >= 0x01000100)
if (dev->config[0].bMaxPower < 250)
#else
if (dev->config[0].MaxPower < 250)
#endif

Installation Instructions for Windows
*************************************
If you are compiling for MinGW or cygwin, please refer to the INSTALL file.
If you are using Microsoft Visual Studio:
- Open the relevant solution file in /msvc:
libusb.dsw for MSVC6, libusb_2005.sln for Visual Studio 2005 or 2008,
libusb_2010.sln for Visual Studio 2010,
libusb_2012.sln for Visual Studio 2012 or later,
libusb_wince.sln for Windows CE support in Visual Studio 2005.
- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define
in msvc\config.h
- Select your configuration and compile the project
Note that if you are using Visual Studio Express, you may have to install the
Windows SDK to be able to compile the 64 bit version of the library.
If you are using the freely available Windows DDK/WDK (Driver Development Kit)
- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define
in msvc\config.h
- Open one of the relevant Free Build or Checked Build prompt for your target
platform
- Navigate to the msvc\ directory where the ddk_build.cmd file is located, and
run 'ddk_build'
- To produce a DLL rather than a static library, use: 'ddk_build DLL'
- To produce a static library that uses LIBCMT[d] instead of MSVCRT[d] (/MT[d]
vs /MD[d] in Visual Studio) use: 'ddk_build /MT'
Note that using the Windows DDK, it is possible to compile both the 32 and 64
bit versions of the library.
If you are building for Windows CE then you will need the Windows CE Standard 5.00 SDK.
Destination directories
***********************
The 32 bit binaries compiled either from Visual Studio or the DDK are placed in
a Win32\ directory at the root of the library
The 64 bit binaries are placed in an x64\ directory
Windows CE binaries are placed in one of the following directories, depending
on the target processor: ARMV4I, MIPSII, MIPSII_FP, MIPSIV, MIPSIV_FP, SH4 or x86.
Troubleshooting
***************
If the compilation process complains about missing libraries, ensure that the
default library paths for your project points to the relevant directories.
If needed, these libraries can be obtained by installing either the latest
Windows SDK or the DDK (Links provided at the end of this file).
For Windows CE it is necessary to install the CE USB Kernel Wrapper driver for
libusb to function on a device.

PORTING LIBUSB TO OTHER PLATFORMS
Introduction
============
This document is aimed at developers wishing to port libusb to unsupported
platforms. I believe the libusb API is OS-independent, so by supporting
multiple operating systems we pave the way for cross-platform USB device
drivers.
Implementation-wise, the basic idea is that you provide an interface to
libusb's internal "backend" API, which performs the appropriate operations on
your target platform.
In terms of USB I/O, your backend provides functionality to submit
asynchronous transfers (synchronous transfers are implemented in the higher
layers, based on the async interface). Your backend must also provide
functionality to cancel those transfers.
Your backend must also provide an event handling function to "reap" ongoing
transfers and process their results.
The backend must also provide standard functions for other USB operations,
e.g. setting configuration, obtaining descriptors, etc.
File descriptors for I/O polling
================================
For libusb to work, your event handling function obviously needs to be called
at various points in time. Your backend must provide a set of file descriptors
which libusb and its users can pass to poll() or select() to determine when
it is time to call the event handling function.
On Linux, this is easy: the usbfs kernel interface exposes a file descriptor
which can be passed to poll(). If something similar is not true for your
platform, you can emulate this using an internal library thread to reap I/O as
necessary, and a pipe() with the main library to raise events. The file
descriptor of the pipe can then be provided to libusb as an event source.
Interface semantics and documentation
=====================================
Documentation of the backend interface can be found in libusbi.h inside the
usbi_os_backend structure definition.
Your implementations of these functions will need to call various internal
libusb functions, prefixed with "usbi_". Documentation for these functions
can be found in the .c files where they are implemented.
You probably want to skim over *all* the documentation before starting your
implementation. For example, you probably need to allocate and store private
OS-specific data for device handles, but the documentation for the mechanism
for doing so is probably not the first thing you will see.
The Linux backend acts as a good example - view it as a reference
implementation which you should try to match the behaviour of.
Getting started
===============
1. Modify configure.ac to detect your platform appropriately (see the OS_LINUX
stuff for an example).
2. Implement your backend in the libusb/os/ directory, modifying
libusb/os/Makefile.am appropriately.
3. Add preprocessor logic to the top of libusb/core.c to statically assign the
right usbi_backend for your platform.
4. Produce and test your implementation.
5. Send your implementation to libusb-devel mailing list.
Implementation difficulties? Questions?
=======================================
If you encounter difficulties porting libusb to your platform, please raise
these issues on the libusb-devel mailing list. Where possible and sensible, I
am interested in solving problems preventing libusb from operating on other
platforms.
The libusb-devel mailing list is also a good place to ask questions and
make suggestions about the internal API. Hopefully we can produce some
better documentation based on your questions and other input.
You are encouraged to get involved in the process; if the library needs
some infrastructure additions/modifications to better support your platform,
you are encouraged to make such changes (in cleanly distinct patch
submissions). Even if you do not make such changes yourself, please do raise
the issues on the mailing list at the very minimum.

libusb is a library for USB device access from Linux, macOS,

It is written in C (Haiku backend in C++) and licensed under the GNU
Lesser General Public License version 2.1 or, at your option, any later
version (see [COPYING](COPYING)).
libusb is abstracted internally in such a way that it can hopefully
be ported to other operating systems. Please see the [PORTING](PORTING)

Notes related to git compilation:
--------------------------------
If you retrieved the libusb repository from git and are using a gcc based
toolchain, be mindful that you should have the autotools installed (autoconf,
automake) and will need to run either ./autogen.sh or ./bootstrap.sh to produce
the configure file.
The difference between autogen.sh and bootstrap.sh is that the former invokes
configure with a default set of options, and will therefore generate a Makefile,
whereas the latter does not invoke configure at all. If using autogen.sh, note
that you can also append options, that will be passed as is to configure.
OS X-specific notes:
-------------------
Starting with Xcode 4.3, neither Xcode.app nor the Xcode 'command line tools'
includes autotools and so running either autogen.sh or bootstrap.sh will result
in the message:
libtoolize or glibtoolize was not found! Please install libtool.
To proceed, you must find and install it from somewhere.
Alternatively, you can use the Xcode project at Xcode/libusb.xcodeproj.
Notes related to submitting new developments:
--------------------------------------------
If you submit a new development to libusb (eg: new backend), that is unlikely
to fit in a couple of small patches, we would kindly suggest that you create a
public account on github, if you don't have one already, and then fork a new
libusb repository under this account from https://github.com/libusb/libusb.
Then you can create a git branch for your work, that we will be able to better
reference and test.
We also suggest that, if you are planning to bring in a large development, you
try to involve the libusb community early by letting the mailing list know, as
you may find that other people might be eager to help you out.
See http://mailing-list.libusb.info for details on how to join the mailing list.

libusb for Android
==================
Building:
---------
To build libusb for Android do the following:
1. Download the latest NDK from:
http://developer.android.com/tools/sdk/ndk/index.html
2. Extract the NDK.
3. Open a shell and make sure there exist an NDK global variable
set to the directory where you extracted the NDK.
4. Change directory to libusb's "android/jni"
5. Run "$NDK/ndk-build".
The libusb library, examples and tests can then be found in:
"android/libs/$ARCH"
Where $ARCH is one of:
armeabi
armeabi-v7a
mips
mips64
x86
x86_64
Installing:
-----------
If you wish to use libusb from native code in own Android application
then you should add the following line to your Android.mk file:
include $(PATH_TO_LIBUSB_SRC)/android/jni/libusb.mk
You will then need to add the following lines to the build
configuration for each native binary which uses libusb:
LOCAL_C_INCLUDES += $(LIBUSB_ROOT_ABS)
LOCAL_SHARED_LIBRARIES += libusb1.0
The Android build system will then correctly include libusb in the
application package (APK) file, provided ndk-build is invoked before
the package is built.
For a rooted device it is possible to install libusb into the system
image of a running device:
1. Enable ADB on the device.
2. Connect the device to a machine running ADB.
3. Execute the following commands on the machine
running ADB:
# Make the system partition writable
adb shell su -c "mount -o remount,rw /system"
# Install libusb
adb push obj/local/armeabi/libusb1.0.so /sdcard/
adb shell su -c "cat > /system/lib/libusb1.0.so < /sdcard/libusb1.0.so"
adb shell rm /sdcard/libusb1.0.so
# Install the samples and tests
for B in listdevs fxload xusb sam3u_benchmark hotplugtest stress
do
adb push "obj/local/armeabi/$B" /sdcard/
adb shell su -c "cat > /system/bin/$B < /sdcard/$B"
adb shell su -c "chmod 0755 /system/bin/$B"
adb shell rm "/sdcard/$B"
done
# Make the system partition read only again
adb shell su -c "mount -o remount,ro /system"
# Run listdevs to
adb shell su -c "listdevs"
4. If your device only has a single OTG port then ADB can generally
be switched to using Wifi with the following commands when connected
via USB:
adb shell netcfg
# Note the wifi IP address of the phone
adb tcpip 5555
# Use the IP address from netcfg
adb connect 192.168.1.123:5555
Runtime Permissions:
--------------------
The default system configuration on most Android device will not allow
access to USB devices. There are several options for changing this.
If you have control of the system image then you can modify the
ueventd.rc used in the image to change the permissions on
/dev/bus/usb/*/*. If using this approach then it is advisable to
create a new Android permission to protect access to these files.
It is not advisable to give all applications read and write permissions
to these files.
For rooted devices the code using libusb could be executed as root
using the "su" command. An alternative would be to use the "su" command
to change the permissions on the appropriate /dev/bus/usb/ files.
Users have reported success in using android.hardware.usb.UsbManager
to request permission to use the UsbDevice and then opening the
device. The difficulties in this method is that there is no guarantee
that it will continue to work in the future Android versions, it
requires invoking Java APIs and running code to match each
android.hardware.usb.UsbDevice to a libusb_device.

The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector

no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field `flag' is not NULL, it points to a variable that is set
to the value given in the field `val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an `int' to
a compiled-in constant, such as set a value from `optarg', set the
option's `flag' field to zero and its `val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero `flag' field, `getopt'
returns the contents of the `val' field. */

missing arguments, `optopt' is set to the option letter, and '?' is

The OPTS string is a list of characters which are recognized option
letters, optionally followed by colons, specifying that that letter
takes an argument, to be placed in `optarg'.
If a letter in OPTS is followed by two colons, its argument is
optional. This behavior is specific to the GNU `getopt'.
The argument `--' causes premature termination of argument
scanning, explicitly telling `getopt' that there are no more
options.

arguments to the option '\0'. This behavior is specific to the GNU

/**
* @defgroup libusb_hotplug Device hotplug event notification
* This page details how to use the libusb hotplug interface, where available.
*
* Be mindful that not all platforms currently implement hotplug notification and
* that you should first call on \ref libusb_has_capability() with parameter
* \ref LIBUSB_CAP_HAS_HOTPLUG to confirm that hotplug support is available.
*
* \page libusb_hotplug Device hotplug event notification
*
* \section hotplug_intro Introduction
*
* Version 1.0.16, \ref LIBUSB_API_VERSION >= 0x01000102, has added support
* for hotplug events on <b>some</b> platforms (you should test if your platform
* supports hotplug notification by calling \ref libusb_has_capability() with
* parameter \ref LIBUSB_CAP_HAS_HOTPLUG).
*
* This interface allows you to request notification for the arrival and departure
* of matching USB devices.
*
* To receive hotplug notification you register a callback by calling
* \ref libusb_hotplug_register_callback(). This function will optionally return
* a callback handle that can be passed to \ref libusb_hotplug_deregister_callback().
*
* A callback function must return an int (0 or 1) indicating whether the callback is
* expecting additional events. Returning 0 will rearm the callback and 1 will cause
* the callback to be deregistered. Note that when callbacks are called from
* libusb_hotplug_register_callback() because of the \ref LIBUSB_HOTPLUG_ENUMERATE
* flag, the callback return value is ignored, iow you cannot cause a callback
* to be deregistered by returning 1 when it is called from
* libusb_hotplug_register_callback().
*
* Callbacks for a particular context are automatically deregistered by libusb_exit().
*
* As of 1.0.16 there are two supported hotplug events:
* - LIBUSB_HOTPLUG_EVENT_DEVICE_ARRIVED: A device has arrived and is ready to use
* - LIBUSB_HOTPLUG_EVENT_DEVICE_LEFT: A device has left and is no longer available
*
* A hotplug event can listen for either or both of these events.
*
* Note: If you receive notification that a device has left and you have any
* a libusb_device_handles for the device it is up to you to call libusb_close()
* on each device handle to free up any remaining resources associated with the device.
* Once a device has left any libusb_device_handle associated with the device
* are invalid and will remain so even if the device comes back.
*
* When handling a LIBUSB_HOTPLUG_EVENT_DEVICE_ARRIVED event it is considered
* safe to call any libusb function that takes a libusb_device. It also safe to
* open a device and submit asynchronous transfers. However, most other functions
* that take a libusb_device_handle are <b>not</b> safe to call. Examples of such
* functions are any of the \ref libusb_syncio "synchronous API" functions or the blocking
* functions that retrieve various \ref libusb_desc "USB descriptors". These functions must
* be used outside of the context of the hotplug callback.
*
* When handling a LIBUSB_HOTPLUG_EVENT_DEVICE_LEFT event the only safe function
* is libusb_get_device_descriptor().
*
* The following code provides an example of the usage of the hotplug interface:
\code

*
* For USB pollable async I/O, you would typically:
* - obtain a Windows HANDLE to a file or device that has been opened in

* - call usbi_create_fd with this handle to obtain a custom fd.
* - leave the core functions call the poll routine and flag POLLIN/POLLOUT
