I added it to the scsi_quirk_inquiry_pattern[] list (in
dev/scsipi/scsiconf.c), using the
 <TOSHIBA , CD-ROM XM-3401TA, 0283> as template.  This is clearly not enough
..

it is now recognized as follow :

cd0 at scsibus0 target 3 lun 0: <TOSHIBA, CD-ROM XM-3401TA, 1534> SCSI2
5/cdrom
removable
cd0: async, 8-bit transfers

but it wont talk to me : neither mount nor dd  succeed to use it ...
Any thoughts ?

Pascal.
