It's not a USB problem.  The device is returning an error code with sense 
key = 0x05 (Illegal Request) and ASC/ASCQ = 0x6f, 0x04 (I don't know what 
those mean).  Maybe someone who is familiar with the SCSI DVD protocol can 
explain.  However it's clear that the low-level USB transport is working 
without errors.
