MAKEDEV cd{0,1,2,3,4,5,6,7,8,9}

1) The `ch' device is wrong, it only applies to tape roboters.

2) If it only sees cd2 (as opposed to cd2 through cd8), you need a
   `quirk' record in /sys/scsi/scsiconf.c, in order to enable multiple
   LUN support for your device.  Look at the entry for the NBR-7
   CD changer as a template.
