Change Details

Tests 1. LIBUSB_ERROR_BUSY - open the same device twice 2. LIBUSB_ERROR_NO_DEVICE - get list of devices, pause, unplug device, attempt to open the unplugged device. 3. LIBUSB_ERROR_ACCESS - get list of devices, pause, alter permissions on the device node, attempt to open a device. 4. LIBUSB_ERROR_INVALID_PARAM - pass a null device handle. 5. LIBUSB_ERROR_NO_MEM - get list of devices, pause, simulate heap full, attempt to open a device. A program covering the above tests - included in Bugzilla - has been run against actual hardware to verify correctness. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291774 Update: a set of twenty one unit tests added. These can be run from kyua and do not require physical hardware.
