    $\begingroup$ Just to nitpick at the puzzle (not that it's bad) ...this bus does not have a driver, the device it is being used with does (or indeed may have many); the bus itself works without a driver and it transports some things without moving prior to the driver even being known or available (power and interface descriptors at least). Oh and a warm welcome to Puzzling both of you (sorry to sound so lame)! $\endgroup$ – Jonathan Allan Jul 27 '16 at 11:02
