 OFW: Q4A13K
 OS: os9.

 Under OFW, test-all reports that "USB 2.0 port 0 is in use". There is
 nothing plugged into any port. (Not sure how the port enumeration works.)

 Under Linux, system fails to boot with log attached -- which also
 complains loudly about USB.

 Wad reports that this unit installed fw/sw and booted at 1CC. The USB port
 may have gotten damaged through use -- OFW, EC and OS were updated via
 USB.
