I'm not sure what the "parameter list" is with regard to ASC/ASCQ and where in the source things related to this might be. I tried to turn on SCSIPI debugging unsuccessfully.

 The problem is that the driver has no ways to know that this is an ATAPI
 device and not a SCSI one (the enclosure announce itself as SCSI). Maybe
 other OSes have specific drivers for this device, or a quirk list.
