2010-05-20USB: testusb: testusb compatibility with FunctionFS gadgetMichal Nazarewicz1-70/+190
The FunctionFS gadget may provide the source/sink interface not as the first interface (with id == 0) but some different interface hence a code to find the interface number is required. (Note that you will still configure the gadget to report idProduct == 0xa4a4 (an "echo 0xa4a4 >/sys/module/g_ffs/parameters/usb_product" should suffice) or configure host to handle 0x0525:0xa4ac devices using the usbtest driver.)

2010-05-20USB: testusb: an USB testing applicationDavid Brownell1-0/+427
The testusb program just issues ioctls to perform the tests implemented by the kernel driver. It can generate a variety of transfer patterns; you should make sure to test both regular streaming and mixes of transfer sizes (including short transfers). For more information on how this can be used and on USB testing refer to <URL:http://www.linux-usb.org/usbtest/>.

This adds an example user-space FunctionFS driver which implements a source/sink interface used for testing.
