:), well I kind of got it into a working mode by looking some more
at the linux code. It seems it need a special MODE_SENSE
command that makes it work like a "normal" scsi device. It should
be dealt with via a quirk or something.

Good idea, I hacked sd.c, because thats the driver that found the
floptical, but thats easily changed...
Well, the drives are out of production, so it has no real value
I just thougt of it as a SCSI floppy drive :) which would be
nice to have at times...
