There are no /dev/scd* devices.

As requested, I have checked "/var/log/messages" and here are the lines
added when the USB CD-ROM drive was plugged in.:
Mar 25 11:20:45 LinuxForensics kernel: usb 1-1: new full speed USB device
using address 2 Mar 25 11:20:47 LinuxForensics kernel: SCSI subsystem
initialized Mar 25 11:20:47 LinuxForensics kernel: Initializing USB Mass
Storage driver...
Mar 25 11:20:47 LinuxForensics kernel: scsi0 : SCSI emulation for USB Mass
Storage devices
And here is the diff between the dmesg output before and after the CD was
plugged in:
261,269d260
< usb 1-1: new full speed USB device using address 2 < SCSI subsystem
initialized < Initializing USB Mass Storage driver...
< scsi0 : SCSI emulation for USB Mass Storage devices < usb 1-1: reset full
speed USB device using address 2 < scsi: Device offlined - not ready after
error recovery: host 0 channel 0 id 0 lun 0 < USB Mass Storage device found
at 2 < usbcore: registered new driver usb-storage < USB Mass Storage support
registered.
Note: I just installed Fedora Core 3 by booting from this USB CD-ROM and
then getting the packages from an FTP server, so I know this CD-ROM drive is
working OK.
Anyone got any ideas?
