5 2012-09-16: v1.0.13-rc1
6 * [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
7 MaxPower was used instead of bMaxPower, as defined in the specs. If your
8 application was accessing the MaxPower attribute, and you need to maintain
9 compatibility with libusb or older versions, see APPENDIX A below.
10 * Fix broken support for the 0.1 -> 1.0 libusb-compat layer
11 * Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
12 * Fix handling of HID and composite devices on Windows
13 * Introduce LIBUSBX_API_VERSION macro
14 * Add Cypress FX/FX2 firmware upload sample, based fxload from
15 http://linux-hotplug.sourceforge.net
16 * Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
17 the drivers allow it, isochronous transfers are not supported yet in libusbx. Also
18 not supported yet is the use of libusb-win32 filter drivers on composite interfaces
19 * Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
20 splitting of bulk transfers
21 * Improve support for newer Intel and Renesas USB 3.0 controllers on Windows
22 * Harmonize the device number for root hubs accross platforms
23 * Other bug fixes and improvements
26 * Fix a potential major regression with pthread on Linux
27 * Fix missing thread ID from debug log output on cygwin
28 * Fix possible crash when using longjmp and MinGW's gcc 4.6
29 * Add topology calls: libusb_get_port_number(), libusb_get_parent() & libusb_get_port_path()
30 * Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
31 * Define log levels in libusb.h and set timestamp origin to first libusb_init() call
32 * All logging is now sent to to stderr (info was sent to stdout previously)
33 * Update log messages severity and avoid polluting log output on OS-X
34 * Add HID driver support on Windows
35 * Enable interchangeability of MSVC and MinGW DLLs
36 * Additional bug fixes and improvements
39 * Revert removal of critical Windows event handling that was introduced in 1.0.10
40 * Fix a possible deadlock in Windows when submitting transfers
41 * Add timestamped logging
42 * Add NetBSD support (experimental) and BSD libusb_get_device_speed() data
43 * Add bootstrap.sh alongside autogen.sh (bootstrap.sh doesn't invoke configure)
44 * Search for device nodes in /dev for Android support
49 * Add libusb_get_version
50 * Add Visual Studio 2010 project files
51 * Some Windows code cleanup
52 * Fix xusb sample warnings
55 * First libusbx release
56 * Add libusb_get_device_speed (all, except BSD) and libusb_error_name
57 * Add Windows support (WinUSB driver only)
66 * Bug fixes and documentation tweaks
67 * Add more interface class definitions
71 * Increase libusb_handle_events() timeout to 60s for powersaving
74 * Use timerfd when available for timer management
77 2009-11-06: v1.0.4 release
78 * Bug fixes including transfer locking to fix some potential threading races
79 * More flexibility with clock types on Linux
80 * Use new bulk continuation tracking in Linux 2.6.32 for improved handling
81 of short/failed transfers
83 2009-08-27: v1.0.3 release
85 * Add libusb_get_max_iso_packet_size()
87 2009-06-13: v1.0.2 release
90 2009-05-12: v1.0.1 release
94 2008-12-13: v1.0.0 release
97 2008-11-21: v0.9.4 release
99 * Add libusb_attach_kernel_driver()
101 2008-08-23: v0.9.3 release
104 2008-07-19: v0.9.2 release
107 2008-06-28: v0.9.1 release
109 * Introduce contexts to the API
110 * Compatibility with new Linux kernel features
112 2008-05-25: v0.9.0 release
113 * First libusb-1.0 beta release

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