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.
