Can you force the device by using the -d <device> switch?

-d <device> is what I use on linux.  Also, I think the first thing tried is to
find a /dev/cdrom...

Perhaps make a link from /dev/cdrom to /dev/cd0?

But there may be a larger problem with the SCSI command set; I don't know at
this level...

I wish I could be more help, but I never did this sort of thing when I was a
FreeBSD user.
