I've seen what looks like the same issue with a 'real' SCSI burner, it
doesn't show up in "cdrecord -scanbus", but is detected properly on
boot and is listed in /proc/scsi/scsi.

strace'ing cdrecord, it appears to be getting returned -ENXIO on
opening any of the /dev/sg* nodes, so it suggests the kernel sg driver
might be at fault here perhaps? /proc/scsi/sg/* lists no devices either.

The only device cdrecord manages to list is my IDE DVD reader which
suggests the direct ATAPI interface is behaving.
