 Occasionally, a USB high speed device (USB mass storage) will be detected
 as a full-speed device instead.  This was detected when OpenFirmware
 failed to find the device in the high-speed list and assumed that no drive
 was present.  The behavior in OpenFirmware has since been fixed, but the
 question as to why the device is detected as a full-speed instead of high
 speed is open.

 Attaching USB traces of a "bad boot" and a "good boot" for comparison.
