USB CDs will appear as SCSI devices, so that device name is /dev/scd0
and not /dev/cdrom.  CD/R/RW will generally show up as /dev/sdx
(because they're writable).  /dev/cdromx is reserved for IDE/ATAPI drives.

What I said above is true for any USB storage device under RH9.  They
will always be presented to the operating system as SCSI devices.  If
the media is writable, it will show up as /dev/sdx (this includes
CD/R/RW, Flash drives, ZIP disks, etc.).  If it's a CDROM (read only)
it'll be /dev/scdx.
