 The USB selftest included in OFW for as long as I can remember (I have a
 short memory) is actually a very low level hardware verification tool.  It
 outputs a fisheye pattern which can be used (in conjuction with an
 oscilloscope) to verify the signal integrity of the USB traces on the
 motherboard.

 In production and in the field, a quicker functional test of the USB ports
 is needed.  I'm not sure what this should be, as the functional test of
 the motherboards is done with a number of peripherals (optical scanner,
 ethernet dongle, and USB key) plugged into the USB ports.

 Perhaps just a check to see that some USB device is connected to each port
 ?
