COPYING_LGPL.txt

                   GNU LESSER GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. 
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.


  This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.

  0. Additional Definitions.

  As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

  "The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

  An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

  A "Combined Work" is a work produced by combining or linking an
Application with the Library.  The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

  The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

  The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

  1. Exception to Section 3 of the GNU GPL.

  You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

  2. Conveying Modified Versions.

  If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

   a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or

   b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.

  3. Object Code Incorporating Material from Library Header Files.

  The object code form of an Application may incorporate material from
a header file that is part of the Library.  You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:

   a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the object code with a copy of the GNU GPL and this license
   document.

  4. Combined Works.

  You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

   a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.

   c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.

   d) Do one of the following:

       0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.

       1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (a) uses at run time
       a copy of the Library already present on the user's computer
       system, and (b) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version.

   e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)

  5. Combined Libraries.

  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 that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

   a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.

   b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.

  6. Revised Versions of the GNU Lesser General Public License.

  The Free Software Foundation may publish revised and/or new versions
of the GNU 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 as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

  If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

libusb-win32-changelog-1.2.6.0.txt

LibUsb-Win32 Change Log
V1.2.6.0 (01/17/2012)
==============================================
* Official release.

* Removed ISO maximum transfer size restrictions/transfer spltting.

* Fixed inf-wizard device notification issue.

V1.2.5.0 (07/23/2011)
==============================================
* Official release.

V1.2.4.9 (07/13/2011) - SNAPSHOT RELEASE
==============================================
* Updated GCC lib file 'libusb.a'

V1.2.4.8 (07/12/2011) - SNAPSHOT RELEASE
==============================================
* Added new public api function 'usb_reset_ex'. This is an extended 
  device reset function which allows developers to specify a port reset, a 
  port cycle, or both. 

* Added new public defines 'USB_RESET_TYPE_XXX' for 'usb_reset_ex' 
  function. 

V1.2.4.7 (07/02/2011) - SNAPSHOT RELEASE
==============================================
* Sync transfers which specify a zero (0) timeout are now considered to be 
  INFINITE. 

V1.2.4.6 (05/12/2011) - SNAPSHOT RELEASE
==============================================
* Added device interface registration. This provides identical 
  functionality to the "DeviceInterfaceGUIDs" supported by WinUSB and 
  libusbK. A device interface guid can be specified in the .inf file. They 
  can be used to quickly locate a usb device or set of USB devices using 
  the setup api as well as device notification registration. 

* New IOCTL codes added to for native libusbK/WinUSB compatibility.
  NOTE: These IOCTLs are currently used only by libusbK.dll.
  o LIBUSB_IOCTL_QUERY_DEVICE_INFORMATION
  o LIBUSB_IOCTL_SET_PIPE_POLICY
  o LIBUSB_IOCTL_GET_PIPE_POLICY
  o LIBUSB_IOCTL_SET_POWER_POLICY
  o LIBUSB_IOCTL_GET_POWER_POLICY
  o LIBUSB_IOCTL_CONTROL_WRITE
  o LIBUSB_IOCTL_CONTROL_READ
  o LIBUSB_IOCTL_FLUSH_PIPE
  o LIBUSBK_IOCTL_CLAIM_INTERFACE
  o LIBUSBK_IOCTL_RELEASE_INTERFACE
  o LIBUSBK_IOCTL_RELEASE_ALL_INTERFACES
  o LIBUSBK_IOCTL_SET_INTERFACE
  o LIBUSBK_IOCTL_GET_INTERFACE

* Renamed main header file (usb.h) to lusb0_usb.h. This eliminates 
  conflicts with the main WDK usb include as well as making the 
  libusb-win32 header more distinguishable from other usb library header 
  files. 

* Added device descriptor caching and active/first config descriptor 
  caching. Descriptor caching prevents unnecessary control requests from 
  interrupting devices that could potentially be in-use. It also makes 
  libusb0.sys more compliant with usb libraries targeting platform where 
  descriptor caching is done automatically. (linux/mac)
  
* Upgraded to libwdi v1.1.1
  o Zadig UI improvements
  o wdi-simple now handles certificate related operations
  o New NSIS (Nullsoft Scriptable Install System) script sample
  o improved INNO Setup script sample
  o libusbK support
  o autogeneration and self-signing of a .cat file, to prevent further security
    prompts during driver installation on Vista and later.
    for more information, see http://libwdi-cps.akeo.ie
  o disable restore point creation during installation
  o Visual Studio 2010 support and overall MS file cleanup
  o use of the Kerberos/e2fsprogs parser in Zadig instead of libconfig

V1.2.4.0 (04/11/2011)
=======================
* Removed get configuration request from the core driver 
  set_configuration function.  This caused problems with
  some non-compliant usb devices.

* Added device descriptor dump to test applications.

V1.2.3.0 (03/16/2011)
=======================
* Fixed bug-id 3117686 reported by Tim Schuerewegen.

* Added LIBUSB_IOCTL_GET_OBJECT_NAME.  This new IOCTL code retrieves object
  from the driver.  The only valid object name index is 0.  Index 0 is
  returns the devices plug and play registry key pathname.

* Removed maximum timeout restriction for vendor class requests.

V1.2.2.0 (10/02/2010)
=======================
* Added install-filter-win.exe.  A gui installer for device filters.

* Added new libusb0.dll function usb_install_np_rundll().  This function
  is designed for rundll32.exe and takes the same parameters as
  install-filter.exe.

* Updated install-filter.exe.  This application has several new features.
  Type "install-filter --help" for more details.

* Updated libusb-win32-devel-filter package.  This package is once again
  available for download as a setup.exe.

* Updated libusb-win32 "bin" package format.  inf-wizard.exe has been moved
  up one directory.

* Updated driver_installer_template.iss example. This is an Inno Setup
  Script showing how to create your own setup.exe for installing your
  application and driver.

* Fixed missing byte order marker in inf-wizard.exe .inf files. (libwdi)

* Fixed auto-configuration issue when there is more than one driver in the
  stack.

* Fixed BSOD when using the filter driver with devices that are auto
  suspended by other drivers in the stack.
  
* Fixed BSOD for devices with endpoints that have '0' for wMaxPacketSize.

* Fixed BSOD when cancelling large transfers on high speed devices.

  
V1.2.1.0 (07/28/2010)
=======================
* Updated bulk.c to include async i/o example code.

* Fixed usb_install_driver_np() issue with inf-wizard generated infs.

* Fixed inf2cat.exe issue with inf-wizard generated infs.
  
* Added 'Install Now' feature to inf-wizard. (libwdi)

* Added embedded libusb-win32 binaries to inf-wizard. (libwdi)

* Added libwdi (http://www.libusb.org/wiki/libwdi) to inf-wizard. 

* Added get cached configuration request to usb_open(). This is a new
  control code that involves no device i/o and allows 
  usb_set_configuration() to be omitted if the driver has already
  configured it.

* Fixed set_configuration() failure for devices that do not properly
  support get_configuration().

V1.2.0.0 (07/07/2010)
=======================
* First signed driver release! The libusb-win32 kernel driver (libusb0.sys)
  can now be used on x64 Windows machines that require signed drivers. 

* Fixed 2128187 reported by Tim Green. usb_get_descriptor() can fail
  because the given buffer of 8 bytes is too small.

* Fixed 2928293 reported by Tim Green. Sometimes the call to 
  usb_fetch_and_parse_descriptors() in usb_find_devices() can fail. This 
  patch moves the LIST_ADD to after a successful read of the device's 
  configuration descriptors.

* Fixed issue causing libusb-win32 to not act as power policy owner
  when it should.

* Fixed issue in which on rare occasion, a libusb-win32 filter device could
  run as a "normal" device.
  
* Fixed filter driver issue for device using wudfr.sys.

* Added large transfer splitting to driver (bulk, int, iso). NOTE:
  The dll continues to break transfers in the same manner it always has.


V1.1.14.3 (06/12/2010)
=======================
* Remove get_configuration() request from usb_open().  This caused claim
  interface to fail when used as a filter driver.
  
V1.1.14.0 (06/01/2010)
=======================
* Updated logging functions and standardized log message display format.

* Updated inf-wizard to use the new directory format for the libusb-win32
  binaries.

* Updated package directories to reflect the winddk BUILDARCH env variable.
  (i64 := ia64, x64 := amd64)
  
* Added request to get the current configuration in usb_open().

* Fixed 2960644 (reported by farthen) crash on shutdown with x64 based
  systems while using inf files for each libusb device.

* Added additional log message only included in debug/chk builds.
  
* Updated default log levels to highest verbose level for debug builds.

* Added test signing support to the libusb-win32 make.cmd. This allows
  libusb0.sys and libusb0.dll to be signed with a digital signature.
  (see make.cmd for mmore details)

* Added MSVC 2008 project files

* Moved version defines to an include file (libusb_version.h)
  This file is generated from libusb_version_h.in with "make.cmd makever"

* Removed all "dist" commands from cyg/mingw makefile.  Instead use "make.cmd"
  in the "ddk_make" directory.

* Fixed filter setup not running in 64bit mode

* Fixed 64bit inf-wizard, testlibusb-win builds

* Added set initial config value #1 when the driver is not a filter.
  optionally, the initial configuration value can be specified in the inf
  file: HKR,,"InitialConfigValue",0x00010001,

* Added support for querying device registry keys 
 (LIBUSB_IOCTL_GET_CUSTOM_REG_PROPERTY)

* Added support for querying device properties 
 (LIBUSB_IOCTL_GET_DEVICE_PROPERTY)

* Fixed possible race condition in kernel add_device()

* Updated default ddk build version number to 1.1.14.0 to facilitate
  Microsoft WHQL submission.

* Added DDK build distribution system.  Official libusb-win32 releases 
 (after 0.1.12.2) are built using Microsoft's WinDDK.  (see make.cmd)

* Fixed 2658937 (reported by Tim Roberts) The libusb-win32 driver always
  acts as a power policy owner.
