USB: testusb: an USB testing application

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/>.
