4 2013-07-01: v1.0.16-rc2
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 * Logging now use a single write call per log-message, avoiding log-message
14 "interlacing" when using multiple threads.
15 * Android: use Android logging when building on Android (#101)
16 * Darwin: make libusb_reset reenumerate device on descriptors change (#89)
17 * Darwin: add support for the LIBUSB_TRANSFER_ADD_ZERO_PACKET flag (#91)
18 * Darwin: add a device cache (#112, #114)
19 * Examples: Add sam3u_benchmark isochronous example by Harald Welte (#109)
20 * Many other bug fixes and improvements
21 The (#xx) numbers are libusbx issue numbers, see ie:
22 https://github.com/libusbx/libusbx/issues/9
25 * Improve transfer cancellation and avoid short read failures on broken descriptors
26 * Filter out 8-bit characters in libusb_get_string_descriptor_ascii()
28 * Add library stress tests
29 * Add Cypress FX3 firmware upload support for fxload sample
30 * Add HID and kernel driver detach support capabilities detection
31 * Add SuperSpeed detection on OS X
32 * Fix bInterval value interpretation on OS X
33 * Fix issues with autoclaim, composite HID devices, interface autoclaim and
34 early abort in libusb_close() on Windows. Also add VS2012 solution files.
35 * Improve fd event handling on Linux
36 * Other bug fixes and improvements
39 * Reverts the previous API change with regards to bMaxPower.
40 If this doesn't matter to you, you are encouraged to keep using v1.0.13,
41 as it will use the same attribute as v2.0, to be released soon.
42 * Note that LIBUSBX_API_VERSION is *decreased* to 0x010000FF and the previous
43 guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.
46 * [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
47 MaxPower was used instead of bMaxPower, as defined in the specs. If your
48 application was accessing the MaxPower attribute, and you need to maintain
49 compatibility with libusb or older versions, see APPENDIX A below.
50 * Fix broken support for the 0.1 -> 1.0 libusb-compat layer
51 * Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
52 * Fix handling of HID and composite devices on Windows
53 * Introduce LIBUSBX_API_VERSION macro
54 * Add Cypress FX/FX2 firmware upload sample, based on fxload from
55 http://linux-hotplug.sourceforge.net
56 * Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
57 the drivers allow it, isochronous transfers are not supported yet in libusbx. Also
58 not supported yet is the use of libusb-win32 filter drivers on composite interfaces
59 * Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
60 splitting of bulk transfers
61 * Improve support for newer Intel and Renesas USB 3.0 controllers on Windows
62 * Harmonize the device number for root hubs across platforms
63 * Other bug fixes and improvements
66 * Fix a potential major regression with pthread on Linux
67 * Fix missing thread ID from debug log output on cygwin
68 * Fix possible crash when using longjmp and MinGW's gcc 4.6
69 * Add topology calls: libusb_get_port_number(), libusb_get_parent() & libusb_get_port_path()
70 * Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
71 * Define log levels in libusb.h and set timestamp origin to first libusb_init() call
72 * All logging is now sent to to stderr (info was sent to stdout previously)
73 * Update log messages severity and avoid polluting log output on OS-X
74 * Add HID driver support on Windows
75 * Enable interchangeability of MSVC and MinGW DLLs
76 * Additional bug fixes and improvements
79 * Revert removal of critical Windows event handling that was introduced in 1.0.10
80 * Fix a possible deadlock in Windows when submitting transfers
81 * Add timestamped logging
82 * Add NetBSD support (experimental) and BSD libusb_get_device_speed() data
83 * Add bootstrap.sh alongside autogen.sh (bootstrap.sh doesn't invoke configure)
84 * Search for device nodes in /dev for Android support
89 * Add libusb_get_version
90 * Add Visual Studio 2010 project files
91 * Some Windows code cleanup
92 * Fix xusb sample warnings
95 * First libusbx release
96 * Add libusb_get_device_speed (all, except BSD) and libusb_error_name
97 * Add Windows support (WinUSB driver only)
106 * Bug fixes and documentation tweaks
107 * Add more interface class definitions
111 * Increase libusb_handle_events() timeout to 60s for powersaving
114 * Use timerfd when available for timer management
115 * Small fixes/updates
117 2009-11-06: v1.0.4 release
118 * Bug fixes including transfer locking to fix some potential threading races
119 * More flexibility with clock types on Linux
120 * Use new bulk continuation tracking in Linux 2.6.32 for improved handling
121 of short/failed transfers
123 2009-08-27: v1.0.3 release
125 * Add libusb_get_max_iso_packet_size()

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