This patch takes advantage of this by not splitting when not necessary. Note that the non-split code path is in essence using the old split code path with an urb count which is always 1. * This leads to more sane handling of large transfers with recent kernels, although our splitting code is well tested, not splitting at all still is a lot better :) * When used with a recent kernel, this also fixes the problems, on XHCI attached devices, when a large bulk-in transfer ends with a short read in an urb other then the last urb. * For more on this see: http://marc.info/?l=linux-usb&m=133797554910355 Conflicts: libusb/os/linux_usbfs.c libusb/version_nano.h commit 7204a06b77b73242403a94eee5227e9e3f874b39 Author: Hans de Goede <hdegoede@redhat.com> Date: Wed Aug 22 11:47:00 2012 +0100 Linux: Add support for the new get_capabilities ioctl * There were a few (new) usbdevfs capabilities which libusbx could not discover in any other way then checking the kernel version. * However, this presents the following problems: 1) It is just not very pretty 2) Given the tendency of enterprise distros to backport stuff it is not reliable 3) Some of these features turn out to not work with certain host controllers, making depending on them based on the kernel version not a good idea * Therefore a new USBDEVFS_GET_CAPABILITIES ioctl has been added to the kernel to offer a better way to find out a device's capabilities (technically the capabilities of the host controller to which the device is attached, but that does not matter).

Bumping the version to 1.0.15 and change the so version. The internal API is changing as follows: - Adding two new functions. usbi_connect_device, and usbi_disconnect_device. Backends must call these functions to add them to the context's device list at one of two places: initial enumeration (done at init), and on device attach and removal. These functions need to be called once per context. - Backends that support hotplug should not provide a get_device_list funtion. This function is now deprecated and will likely be removed when all backends support hotplug. The external API is changing as follows: - Several new functions have been added to register for notification of device attach/detach. Callbacks are per context and can be called once or persist for the lifetime of the context. - Details of the new functionality can be found in libusb.h commit 2574334e8c46b2d86f2c1b920195f917368554ef Author: Nathan Hjelm <hjelmn@me.com> Date: Thu Nov 29 13:53:41 2012 -0700 cache device descriptors in the core commit 30e02dee5840de7c0835fc5a31f2e544b6e45bd5 Author: Nathan Hjelm <hjelmn@me.com> Date: Thu Nov 29 13:46:07 2012 -0700 Fix #150: do not unsuspend Apple devices by checking for idProduct == kIOUSBVendorIDAppleComputer commit 319e3a4297986aee16f7a4b6f3d23ef0bdaf7e03 Author: Nathan Hjelm <hjelmn@me.com> Date: Sun Sep 30 11:49:01 2012 -0600 core: Keep a list of contexts (active_contexts_list) created by libusb_init.

By arming or disarming the timerfd during completion strictly according to remaining flying transfers while also holding the flying_transfers_lock this change ensures that a new transfer can not be added to the flying list until the completion code path has armed/disarmed the timerfd according to the current flying list.

The commit unfortunately also broke the logic during transfer completion which decides if the timerfd will be disarmed or not, and disarm_timerfd() was called even if the timerfd had already been armed with the next flying transfer timeout. Before the offending commit the timerfd would be disarmed only when arm_timerfd_for_next_timeout() reported that there was no flying transfer with a timeout. Let's restore that behavior. The bug was spotted through code review both by the author and by Hans de Goede, but was not squashed until Vincent Pellier experienced transfers never timing out, and helped confirm the source of the problem. Many thanks!

This could cause a deadlock when attempting to lock the event lock if another thread was processing events on the just-submitted transfer. The deadlock comes about as the thread calling libusb_submit_transfer() acquires the transfer mutex before trying to acquire the event lock; this is the other order of lock acquisition from an event thread handling activity on the just submitted transfer. This could lead to one of two deadlocks: 1) If the transfer completes while usbi_fd_notification() is waiting for the event lock and the callback attempts to resubmit the transfer. 2) If the transfer timeout is hit while usbi_fd_notification() is waiting for the event lock then the attempt to cancel the transfer will deadlock. This patch fixes both of these deadlocks by having libusb_submit_transfer() only call usbi_fd_notification() after having released the transfer mutex. This deadlock was always present in the Windows code, but temporarily deleted by mistake in commit 6506013c6d4face34cfec79dd0584e9f528cbc6a and later restored in commit 325a8416697cf69b9b926ed68720f12b1aedf940. libusbx.git commit 1ed09c7b2a5fc27c3cfea21740584879781bff67 [stuge: Touch up commit message] commit b988c3d66e349b4f3c430410a42b6203f4fef80f Author: Peter Stuge <peter@stuge.se> Date: Sun Jun 3 21:28:13 2012 +0200 Clean up broken whitespace in list_for_each_entry() macros Introduced by commit aa77b02da65afb0332b9e6853dae9e4dcda00bfa. commit f651b2669c6ab0804d572650d79551bc2b70f525 Author: Peter Stuge <peter@stuge.se> Date: Tue May 8 19:50:17 2012 +0200 examples: Add sam3u_benchmark isochronous example by Harald Welte Copied with the author's permission under LGPL-2.1 from usb-benchmark-project/host/benchmark.c in git://git.gnumonks.org/sam3u-tests.git commit 74959f7ee88f1597286cd435f312a8ff52c56b7e http://git.gnumonks.org/cgi-bin/gitweb.cgi?p=sam3u-tests.git;a=blob;f=usb-benchmark-project/host/benchmark.c;h=74959f7ee88f1597286cd435f312a8ff52c56b7e An Atmel SAM3U test firmware is also available in the above repository. commit 3a69eff1aaf8e3242937bd7ecc94a60e7aa502cd Author: Peter Stuge <peter@stuge.se> Date: Tue May 8 19:22:31 2012 +0200 examples: Only check for HAVE_SIGACTION once in Makefile.am commit d9dbb433f3f3b9787417e34316604d99cb72b188 Author: Peter Stuge <peter@stuge.se> Date: Tue May 8 19:19:28 2012 +0200 .gitignore: Add examples/ path to the examples commit a129732fb45fc424743f26f01c906e4514f11521 Author: Peter Stuge <peter@stuge.se> Date: Tue May 8 19:14:40 2012 +0200 examples: Use a common LDADD for all examples commit 325a8416697cf69b9b926ed68720f12b1aedf940 Author: Uri Lublin <uril@redhat.com> Date: Tue May 1 16:47:34 2012 +0300 Windows: Make new transfers correctly notify the event handling thread usbi_fd_notification() calls are added back into submit_*_transfer() so that the event handling thread will be aware of new transfers. libusb.git commit 6506013c6d4face34cfec79dd0584e9f528cbc6a from libusbx.git commit 4cccbed825fe1dc138121640a6497d7d05aac159 removed these calls during the removal of the DYNAMIC_FDS Windows-specific [stuge: Rewrite commit message] commit 4674b4d137df2e2e49a1057c947888de8f37d6e8 Author: Ludovic Rousseau <ludovic.rousseau+github@gmail.com> Date: Fri Apr 20 22:25:38 2012 +0100 Linux: Fix warning: comparison between signed and unsigned libusbx.git commit 36a7119bf296cecd4e910bef86908fd782224960 commit ab9cd5a7be637f7b793987971a706b1d11c27ded Author: Peter Stuge <peter@stuge.se> Date: Fri Apr 20 08:10:11 2012 +0200 libusb-1.0.9 commit 696400ad83531bcf944c71164a46f9ccb6a33df3 Author: Peter Stuge <peter@stuge.se> Date: Fri Apr 20 08:08:34 2012 +0200 AUTHORS: Update list of contributors commit 19f94537ea55586dd85f8d627fcfaa6173069ea1 Author: Peter Stuge <peter@stuge.se> Date: Fri Apr 20 06:41:34 2012 +0200 AUTHORS: Add Martin Pieuchot as copyright holder commit 1a1c633d7912a2565f6af0c9294e10a759d40e05 Author: Peter Stuge <peter@stuge.se> Date: Fri Apr 20 06:41:12 2012 +0200 AUTHORS: Add Hans de Goede as copyright holder commit 9477f793341d59cc861acb283e6cb03b5730ac91 Author: Peter Stuge <peter@stuge.se> Date: Fri Apr 20 06:40:45 2012 +0200 AUTHORS: Add Peter Stuge as copyright holder commit 4b0dfe9770356af3c51103a9b3d63c5f8cc63d8b Author: Pete Batard <pete@akeo.ie> Date: Mon Apr 2 15:47:53 2012 +0100 AUTHORS: Update Pete Batard's copyright years and email address libusbx.git commit f98eaca0985364be00fcfde3fd3884075092a4e9 [stuge: Remove unrelated changes] commit 9f0ea78357b7b1654cb3e7de6ff57f5f378b68f1 Author: Peter Stuge <peter@stuge.se> Date: Fri Apr 20 08:35:04 2012 +0200 AUTHORS: Update Nathan Hjelm's copyright years commit 8d38506ebc9fb57a40113e5a7739572a42b826d8 Author: Peter Stuge <peter@stuge.se> Date: Fri Apr 20 06:36:08 2012 +0200 README: Add the BSDs, punctuation, mailinglist link, and remove Daniel commit 05cbe2de45806db309343cdf298d8569c55863e5 Author: James Hanko <james.hanko@tridentmicro.com> Date: Wed Oct 19 17:32:34 2011 -0700 Linux: Search for /dev/usbdev<bus>.<device> USB device special files If neither the (now deprecated) usbfs filesystem nor udev is available then libusb searches for device nodes also in /dev where they may be created if the kernel was built with the option CONFIG_USB_DEVICE_CLASS.

Instead of just fixing this one case I've audited (and fixed where necessary) all handle_foo_completion() functions to know about all errors documented in linux/Documentation/usb/error-codes.txt. Note that for handle_iso_completion() this patch actually removes the handling of some codes, since these can never occur on an iso urb (they can only occur on the iso packets included in the urb, see the next patch in this series). Also, in case an unknown status is encountered on an iso urb this patch sets the urb's status to ERROR rather then leaving it at completed. Signed-off-by: Hans de Goede <hdegoede@redhat.com> commit 98bc7b8d125c2756deadfc889dcefd4e6f2fcd02 Author: Hans de Goede <hdegoede@redhat.com> Date: Fri Mar 9 11:31:07 2012 +0100 Don't print an error when libusb_cancel_transfer() fails with NOT_FOUND As stated in the documentation for libusb_cancel_transfer(), LIBUSB_ERROR_NOT_FOUND is an expected return value for libusb_cancel_transfer() under certain circumstances, so printing an error every time this happens is undesirable. Even more so because under Linux IOCTL_USBFS_DISCARDURB sets errno to EINVAL when the kernel can't not find the urb in the kernel's urbs-in-flight list, which means that the urb has already completed at the host controller level but it has not necessarily been reaped yet. IOW under Linux libusb_cancel_transfer() may yield a result of LIBUSB_ERROR_NOT_FOUND *before* the transfer's callback has been called! In conclusion there is no way for applications to avoid calling libusb_cancel_transfer() on already completed transfers, and these errors can and do happen frequently for some USB traffic.

But if we've successfully cancelled the last urb, and then another urb fails with errno == EINVAL, this means that we've still cancelled the transfer, as it has only *partially* completed.

This flag allows applications to inform libusb about this requirement, so that libusb can handle the issue transparently. At the moment the new flag is only supported on Linux, and submitting a transfer with the flag set returns an error at submit time on other systems. Hopefully implementations will soon follow for other systems.

a NULL pointer for the tv argument (I interpreted it like that when I first started coding for libusb). This patch changes the docs to make it clear that one must always supply a tv struct to libusb_handle_events_timeout.

As http://libusb.org/ticket/81#comment:14 notes there is still another possible, but unlikely, race condition between libusb_submit_transfer() and an event handling thread. That will require more work to solve.

However, the check was done outside of the lock that is held while the condition is set, so another thread could completely serve whatever was needed to make the condition true between it being checked and the event handler being called. This situation would be detected after a libusb-internal timeout of 60 seconds, after which the transfer would be completed without error, but with significant delay.

So if an app has detached the in kernel driver, and claimed the interface and then does a libusb_reset_device. Things end up with the interface no longer being bound to the usbfs driver (so no longer claimed) and instead it is bound to the in kernel driver (iow the in kernel driver is re-attached). We can stop this from happening by releasing all claimed interfaces before the reset, as the kernel will not do the device attach after reset, if no driver was bound to the interface before the reset.

Using the old method, a race condition could occur if a device was unplugged just before (or during) the call to libusb_get_device_list(), corrupting the internal sysfs_can_relate_devices and sysfs_has_descriptors variables and preventing libusb_get_device_list() from working in future calls. The old method was based on the assumption that if certain sysfs files (eg: busnum) could not be opened, that indicated an inadequacy of sysfs (ie: the running kernel's sysfs version did not contain those files), when in reality those files couldn't be opened because the device had been unplugged. The new method checks the adequacy of sysfs during libusb_init() (op_init()) and if a sysfs file cannot be opened, it is now assumed that it is because the device has been unplugged, not because sysfs is inadequate.

The Windows resource file libusb/libusb-1.0.rc must include the release version, which was previously only available after configure had run and had substituted the numbers into a generated libusb/libusb-1.0.rc file. The version atoms are now stored as CPP style #defines in libusb/version.h so that the .rc no longer needs to be generated but can simply include the header file and access the version information directly. The m4 macro LU_DEFINE_VERSION_ATOM() was added to configure.ac to get version atoms from libusb/version.h for use in AC_INIT(). The macro handles C and C++ style comments in version.h, but can easily be made to fail by obscuring the file. Please don't do that. Tested with MinGW using autoconf, and manual compile of libusb-1.0.rc using RC.EXE Version 5.2.3690.0 from Visual C++ 2005 Express Edition. commit 3481f52b014110f6c291e5a15e79ba774dcdfacf Author: Peter Stuge <peter@stuge.se> Date: Tue May 10 08:36:32 2011 +0200 Windows: Debug builds create the same .dll file name as non-debug Thanks to Pete for pointing this out! commit 9da8cf5c9ed9bd381a77d8170fc0556edbcce4dc Author: Pete Batard <pbatard@gmail.com> Date: Tue Mar 8 17:18:48 2011 +0000 Windows: explicit use of ANSI or WideChar calls * This is in anticipation of adding MSVC project files that use Unicode rather than MBCS commit ae675c1f49dc00b695fce7296903f60998cc28ed Author: Pete Batard <pbatard@gmail.com> Date: Tue Mar 8 17:16:23 2011 +0000 Windows: Remove SetupAPI, AdvAPI32 and OLE32 link-time dependencies * this ensures that libusb dependent applications only need to explicitly link against libusb on Windows The run-time dependency on Cfgmgr32.dll, OLE32.dll and SetupAPI.dll remains. commit 356e312511e4892977636da52ec497ad2c716032 Author: Pete Batard <pbatard@gmail.com> Date: Tue Mar 8 17:12:33 2011 +0000 Add .gitattributes to avoid Windows line ending issues with autocrlf commit 61c120f025f3dee04eeb88159d7c0403a8bf91fe Author: Peter Stuge <peter@stuge.se> Date: Sun Feb 27 09:37:54 2011 +0100 Windows: Touch up FileDescription and ProductName resource strings commit 99b4ddcd893834a4be8b5884037b650e57ba0ba2 Author: Peter Stuge <peter@stuge.se> Date: Sun Feb 27 07:20:40 2011 +0100 Windows: Remove emulated direct device access via HID API Either use a library such as HIDAPI to communicate with HID class devices, or replace the kernel driver for the device with one that offers support for the complete libusb API. commit 4be84ab49c838d534d3a1b8a64ffa89774984ee7 Author: Peter Stuge <peter@stuge.se> Date: Sun Feb 27 06:59:15 2011 +0100 Revert libusb_strerror() until we have i18n and l10n commit 0e177f22fcc69d9aab6fb410e85f3413f478c94c Author: Pete Batard <pbatard@gmail.com> Date: Wed Jan 19 14:00:12 2011 +0000 dpfp_threaded: return instead of pthread_exit() to avoid Cygwin warning commit e65878f21b0a0bb96debcb292dc03ce3c4ebb701 Author: Pete Batard <pbatard@gmail.com> Date: Wed Jan 19 13:52:08 2011 +0000 Windows: Rename various variables named "index" to avoid shadow warnings commit 019bf73bb2677dc7720bc8280527316adcbaa506 Author: Pete Batard <pbatard@gmail.com> Date: Tue Oct 5 12:50:53 2010 +0100 Windows: Fix logic in enumeration of driver name and port number commit 24494ed5db27737fc607fc35dda722521c9fe4d4 Author: Pete Batard <pbatard@gmail.com> Date: Tue Oct 5 12:50:13 2010 +0100 Windows: Allow claiming any interface in composite device using WinUSB Issue reported by Benjamin Dobell, see #48.

Linker flags must thus always be specified with -Wl. Factor out the libtool flag -no-undefined from host specific cases. The flag is required to build a Windows DLL, but is correct also for the other supported systems. Also, start actually using LTLDFLAGS in libusb/Makefile.am, so that libtool will see the options set by configure. commit 3cbe5736469c1c52049752c137ae11387e9b079d Author: Peter Stuge <peter@stuge.se> Date: Sun Nov 21 23:38:46 2010 +0100 configure.ac: Clean up PC_LIBS_PRIVATE and AM_LDFLAGS Move linker options for when linking the library itself from PC_LIBS_PRIVATE into AM_LDFLAGS.

Since libusb has an internal 60 second timeout this bug could not cause complete lockup, but it could cause a 60 second timeout even when a transfer was submitted with a shorter timeout. commit 7802e4a3e38bcefccf96ae510ec2c6b7a959b8b5 Author: Ludovic Rousseau <rousseau@debian.org> Date: Mon Nov 15 14:55:51 2010 +0100 Linux: Correctly catch read() errors for sysfs config descriptors read(2) returns ssize_t (signed) and not size_t (unsigned) or int.

Many thanks to Brian Shirley and National Instruments for finding and fixing this! commit 116d34f608b02f4e14668450b158acf5db726f95 Author: Pete Batard <pbatard@gmail.com> Date: Tue Oct 5 12:43:41 2010 +0100 Windows: add support for filter drivers * precedence is driver > upper filter > lower filter, and defined in struct driver_lookup lookup from set_device_paths() commit eb833fcd837e3aac2e497438b14c8612254c28ce Author: Pete Batard <pbatard@gmail.com> Date: Tue Oct 5 12:36:49 2010 +0100 Windows: fix errcode shadow warning, and string and DLL_DECLARE fixes * use FormatMessageA, and overall improvement of windows_error_str() * use safe_strlen() always * better typing/init default * more explicit debug message for devices with no driver commit 1feadb5f78e1d2cdfd2aaf0011e041c2848bae37 Author: Pete Batard <pbatard@gmail.com> Date: Tue Oct 5 12:29:32 2010 +0100 Windows: use IOCTLs for HID input, output and feature reports * fixes feature reports not providing actual read size (reported by Axel Rohde http://marc.info/?m=127033070021994) * removes the USE_HIDD_FOR_REPORTS macro * IOCTL usage inspired from HIDAPI by Alan Ott commit d7c25451f4075d2a12eb5cbc91ff3de8c0292da0 Author: Daniel Drake <dan@reactivated.net> Date: Mon Oct 4 20:03:58 2010 +0100 Fix libtool version setting This was being set too early to take effect. commit a6fb54e2eef4e393bd06829bc3bdc746ea9d41a6 Author: Mike Frysinger <vapier@gentoo.org> Date: Mon Oct 4 20:01:07 2010 +0100 Populate the pkg-config Libs.private field commit a9b4065f048e750b7317f6434406fd528b69bf33 Author: Mike Frysinger <vapier@gentoo.org> Date: Fri Aug 20 00:09:46 2010 -0400 Linux: fix build failure when CLOCK_MONOTONIC does not exist This is not available on all platforms. commit d192c5bd32736fde0080d756de6221287af34891 Author: Daniel Drake <dan@reactivated.net> Date: Mon Oct 4 18:45:18 2010 +0100 Update libtool version info With input from various people on the mailing list, update the libtool versioning info and start to update this on every release.

Match the Windows API calling convention and document this appropriately. This calling convention will be used regardless of the configuration of the user's development platform. The only user-level complication is that all functions used as libusb callbacks must use the same calling convention as libusb. The LIBUSB_CALL macro is provided to make this easy.

This flag, which is expected to be available in usbfs starting with kernel 2.6.32, allows the kernel to cancel multiple URBs upon receipt of a short packet. This capability allows libusb to preserve data integrity of large bulk transfers that are split into multiple URBs. Without this support, these URBs must be canceled in userspace upon receipt of a short packet, a race condition against future transfers which might partially fill these canceled URBs. This patch automatically detects whether a supported kernel is present and enables the use of the flag when possible. [dsd: tweaks to supported kernel detection, and some inline documentation of this mechanism] commit 69830057547396f893f0d7b3125a05d016313b10 Author: Daniel Drake <dsd@gentoo.org> Date: Wed Oct 28 15:13:22 2009 +0545 Transfer locking At least on Linux, there were some possible races that could occur if a transfer is cancelled from one thread while another thread is handling an event for that transfer, or for if a transfer completes while it is still being submitted from another thread, etc. On the global level, transfers could be submitted and cancelled at the same time.

Signed-off-by: David Moore <dcm@acm.org> commit d2a8ec2da8abcd8f4648ed118da16191011982dd Author: David Moore <dcm@acm.org> Date: Wed Jan 7 22:31:09 2009 -0800 Linux: Fix race condition in cancel_bulk_transfer() This fixes a race condition in cancel_bulk_transfer(). In the old version, awaiting_reap and awaiting_discard are incremented in cancel_bulk_transfer() and decremented in handle_bulk_completion(). However, since these events may take place in two different threads, these variables may reach zero before all URBs have been canceled, triggered spurious callbacks and duplicate frees. This changes the logic to use a single variable "num_retired" to replace both awaiting_reap and awaiting_discard. num_retired is incremented only in handle_bulk_completion() and thus there is no race. The handler will know that all URBs have been canceled when num_retired becomes equal to num_urbs. This change also simplifies a great deal of the logic in both functions and is a net reduction in the amount of code. Note that some variables such as "reap_action" probably need to still be protected by a mutex, and this patch does not address that issue.

Fix this by adding an internal control pipe, which the close routines use to interrupt the event handler and obtain the event handling lock, ensuring that no other thread is handling events while the device is closed. After the close completes, it signals all the event handlers to start up again using the usual mechanism.

Add a temporary hack to libusb_event_handler_active() so that at least the other threads will realise on the next iteration of their event handling loop. The real fix will likely involve reworking most of this. commit 514bb8790cfe8b93ccfff82bc17081b1030acce0 Author: Daniel Drake <dsd@gentoo.org> Date: Thu May 29 12:35:01 2008 +0100 Refine libusb_set_configuration() semantics Applications will generally want to set a configuration before claiming interfaces. The problem is that the interface may already be set, and someone else may have claimed an interface (meaning that all calls to set_configuration will fail, even if it's for the same configuration). There are now 2 options: 1. Use the new libusb_get_configuration() to determine active configuration before calling libusb_set_configuration() 2. Or just call libusb_set_configuration() as usual, which will do nothing if that configuration is already active. commit d1292f8e7300051239a7ed2769d221dc7a6f9fca Author: Daniel Drake <dsd@gentoo.org> Date: Sun May 25 23:42:42 2008 +0100 v0.9.0 release First libusb-1.0 beta release commit 4cd249388e4ed2ca03f1263984ab67df5030bb65 Author: Daniel Drake <dsd@gentoo.org> Date: Sun May 25 22:59:09 2008 +0100 Take lock before raising event waiters condition This avoids a race between the user checking for active event handler and then blocking on the condition variable commit 7c525480ab3c4db9205bfe30bb0d2bef9096c444 Author: Daniel Drake <dsd@gentoo.org> Date: Fri May 23 15:57:07 2008 +0100 Implement serialization of event handlers Now offers a mechanism to wait for events while another thread is doing the event handling.

Now we're much more similar to the Linux kernel model.

Each libusb_device now has a reference count, defaulting to 1 on instantiation. The reference count of 1 refers to the fact that it is present in the list in this scenario. Opening a device adds a pointer to the libusb_device structure in the handle, so that also adds a reference. Closing the device removes that reference. The function to free the device list can optionally unref all the devices inside. In future we will make the libusb_device instances all "global" so that if the app calls get_device_list twice it actually gets the same libusb_device structure references back. This way we can start to track disconnects, and we can investigate adding a unique "session ID" to each libusb_device, an identifier guaranteed to be unique to that device until reboot. commit 77cea822788e024c848c7f554915f771a2dc1e0f Author: Daniel Drake <dsd@gentoo.org> Date: Thu Mar 6 17:05:04 2008 +0000 Remove ctrl debug code This was unintentionally committed commit b873521a6f575628d535f89278bb67888004d0ca Author: Daniel Drake <dsd@gentoo.org> Date: Tue Feb 26 22:11:34 2008 +0000 Notifications for changes to the fd set Applications can now be notified when they should start and stop polling new file descriptors. commit ca66e16a370c828d08a5bc3f9f203db145c81a4c Author: Daniel Drake <dsd@gentoo.org> Date: Fri Feb 1 12:20:20 2008 +0000 Fix header installation path commit e583100a4086c411093eef5c450880b965df6b1b Author: Daniel Drake <dsd@gentoo.org> Date: Wed Jan 30 13:24:54 2008 +0000 TODO update commit 637a8d7ff8a11a23588925d9d3003a609bda8075 Author: Daniel Drake <dsd@gentoo.org> Date: Wed Jan 30 13:19:10 2008 +0000 Remove timers and signalfd Instead of timers, add a mechanism for informing the parent app when the next timeout is due to happen, so that it can call us at that time.

Instead, using "libusb_" should be safer. commit e9364d72151ae1de9cce4175f330fe1529f02511 Author: Daniel Drake <dsd@gentoo.org> Date: Fri Jan 4 00:40:49 2008 +0000 Rename to libusb-1.0 I've taken over the libusb project, and what was previously known as fpusb will eventually be released as libusb-1.0. commit f4ed0b6a3e0a20555fdfc9e9b8be7e8a2c8ae192 Author: Daniel Drake <dsd@gentoo.org> Date: Sun Dec 30 22:09:50 2007 +0000 Compiler flags update Also fix some warnings commit d3d671efe27491baf1d2ceadbfeeb4e7428d6f9a Author: Daniel Drake <dsd@gentoo.org> Date: Sun Dec 30 22:05:17 2007 +0000 Fix signalfd structure size on x86 ptr is a 64-bit value commit dfac6756faad76071a92945e3e3a16b8a841a7ea Author: Daniel Drake <dsd@gentoo.org> Date: Wed Dec 12 23:32:54 2007 +0000 Don't pass ctrl_msg/bulk_msg structures through async paths These are easiest to construct on the stack, but in the async case it is likely that the submitting function returns (hence stack is destroyed) before URB completion. commit a8d2881eb7c273892acf2ff6e1f3f552631d1d11 Author: Daniel Drake <dsd@gentoo.org> Date: Mon Dec 3 23:29:22 2007 +0000 Add functionality to access device descriptors commit b5a7a411087b37a6bf56b4688a9e3290daaed153 Author: Daniel Drake <dsd@gentoo.org> Date: Mon Dec 3 22:27:21 2007 +0000 Rename fpusb_device_handle functions to devh Prevents confusion with functions that work on fpusb_dev structures. commit eacf4505a473df0f521d1b69d5b45448f0709e2d Author: Daniel Drake <dsd@gentoo.org> Date: Sun Dec 2 23:16:57 2007 +0000 Add API to access poll fd Almost forgot... :) commit 852bba4754ec57679c823f33e8feba6e4a564cbe Author: Daniel Drake <dsd@gentoo.org> Date: Wed Nov 28 13:48:45 2007 +0000 Initial commit Basic library structure which supports enumerating detected USB devices |
