When multiple threads are involved receiving completion events in LibUSB

2018-09-28T10:28:22Z

make sure there is always a master polling thread, by setting the "ctx_handler" field in the context. Else the reception of completion events can stop. This happens if event threads are created and destroyed during runtime. Found by: Ludovic Rousseau PR: 231742 MFC after: 1 week Approved by: re (kib) Sponsored by: Mellanox Technologies

Fix issues about cancelling USB transfers in LibUSB when the USB device has

been detached. When a USB device has been detached the kernel file handle stops responding to commands. USB applications which continue to run after the USB device has been detached, depend on LibUSB generated events to tear down its pending USB transfers. Add code to handle the needed cleanup when processing the USB transfer(s) fails and prevent new USB transfer(s) from being submitted.

lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

libusb(3): Expose device caps as libusb_bos_descriptor::dev_capability

2017-08-09T18:06:27Z

Some libusb consumers in Linux-land (in this case, libusb4java) expect a dev_capability member that they can use to enumerate the device capabilities. No particular layout is expected of this, just that it can be traversed using the bLength member until bNumDeviceCapabilities are read and that the consumer may then use one of the libusb_get_*_descriptor methods to extract specific (usb 2.0 vs. ss) capability information.
