One of the configurations I tried had the normal CD as slave on the same
bus as my hard disk, with the CD burner on its own chain. It was set to
"master," but there was no other device. It seemed to talk to the machine

On further reading of the docs, it seems that -scanbus only works under
FreeBSD with CAM right now, as far as BSDs go. The message reported was
the same in the case of each command, anyway. It complained of not finding
a SCSI driver. (The -scanbus option did hit the drive activity light on
the CD burner, so I don't know if the functionality is broken or what...)

I didn't follow the code through, but it looked to me (from an initial
glance) that it tried to distinguish between ATAPI and SCSI under NetBSD.
I'd have to look harder to be sure of that, though.
