2 visit: http://log.libusbx.org
5 * Add hotplug support for Darwin and Linux (#9)
6 * Add superspeed endpoint companion descriptor support (#15)
7 * Add BOS descriptor support (#15)
8 * Make descriptor parsing code more robust
9 * New libusb_get_port_numbers API, this is libusb_get_port_path without
10 the unnecessary context parameter, libusb_get_port_path is now deprecated
11 * New libusb_strerror API (#14)
12 * New libusb_set_auto_detach_kernel_driver API (#17)
13 * Improve topology API docs (#95)
14 * Logging now use a single write call per log-message, avoiding log-message
15 "interlacing" when using multiple threads.
16 * Android: use Android logging when building on Android (#101)
17 * Darwin: make libusb_reset reenumerate device on descriptors change (#89)
18 * Darwin: add support for the LIBUSB_TRANSFER_ADD_ZERO_PACKET flag (#91)
19 * Darwin: add a device cache (#112, #114)
20 * Examples: Add sam3u_benchmark isochronous example by Harald Welte (#109)
21 * Many other bug fixes and improvements
22 The (#xx) numbers are libusbx issue numbers, see ie:
23 https://github.com/libusbx/libusbx/issues/9
26 * Improve transfer cancellation and avoid short read failures on broken descriptors
27 * Filter out 8-bit characters in libusb_get_string_descriptor_ascii()
29 * Add library stress tests
30 * Add Cypress FX3 firmware upload support for fxload sample
31 * Add HID and kernel driver detach support capabilities detection
32 * Add SuperSpeed detection on OS X
33 * Fix bInterval value interpretation on OS X
34 * Fix issues with autoclaim, composite HID devices, interface autoclaim and
35 early abort in libusb_close() on Windows. Also add VS2012 solution files.
36 * Improve fd event handling on Linux
37 * Other bug fixes and improvements
40 * Reverts the previous API change with regards to bMaxPower.
41 If this doesn't matter to you, you are encouraged to keep using v1.0.13,
42 as it will use the same attribute as v2.0, to be released soon.
43 * Note that LIBUSBX_API_VERSION is *decreased* to 0x010000FF and the previous
44 guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.
47 * [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
48 MaxPower was used instead of bMaxPower, as defined in the specs. If your
49 application was accessing the MaxPower attribute, and you need to maintain
50 compatibility with libusb or older versions, see APPENDIX A below.
51 * Fix broken support for the 0.1 -> 1.0 libusb-compat layer
52 * Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
53 * Fix handling of HID and composite devices on Windows
54 * Introduce LIBUSBX_API_VERSION macro
55 * Add Cypress FX/FX2 firmware upload sample, based on fxload from
56 http://linux-hotplug.sourceforge.net
57 * Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
58 the drivers allow it, isochronous transfers are not supported yet in libusbx. Also
59 not supported yet is the use of libusb-win32 filter drivers on composite interfaces
60 * Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
61 splitting of bulk transfers
62 * Improve support for newer Intel and Renesas USB 3.0 controllers on Windows
63 * Harmonize the device number for root hubs across platforms
64 * Other bug fixes and improvements
67 * Fix a potential major regression with pthread on Linux
68 * Fix missing thread ID from debug log output on cygwin
69 * Fix possible crash when using longjmp and MinGW's gcc 4.6
70 * Add topology calls: libusb_get_port_number(), libusb_get_parent() & libusb_get_port_path()
71 * Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
72 * Define log levels in libusb.h and set timestamp origin to first libusb_init() call
73 * All logging is now sent to to stderr (info was sent to stdout previously)
74 * Update log messages severity and avoid polluting log output on OS-X
75 * Add HID driver support on Windows
76 * Enable interchangeability of MSVC and MinGW DLLs
77 * Additional bug fixes and improvements
80 * Revert removal of critical Windows event handling that was introduced in 1.0.10
81 * Fix a possible deadlock in Windows when submitting transfers
82 * Add timestamped logging
83 * Add NetBSD support (experimental) and BSD libusb_get_device_speed() data
84 * Add bootstrap.sh alongside autogen.sh (bootstrap.sh doesn't invoke configure)
85 * Search for device nodes in /dev for Android support
90 * Add libusb_get_version
91 * Add Visual Studio 2010 project files
92 * Some Windows code cleanup
93 * Fix xusb sample warnings
96 * First libusbx release
97 * Add libusb_get_device_speed (all, except BSD) and libusb_error_name
98 * Add Windows support (WinUSB driver only)
107 * Bug fixes and documentation tweaks
108 * Add more interface class definitions
112 * Increase libusb_handle_events() timeout to 60s for powersaving
115 * Use timerfd when available for timer management
116 * Small fixes/updates
118 2009-11-06: v1.0.4 release
119 * Bug fixes including transfer locking to fix some potential threading races
120 * More flexibility with clock types on Linux
121 * Use new bulk continuation tracking in Linux 2.6.32 for improved handling
122 of short/failed transfers
124 2009-08-27: v1.0.3 release

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