hi,

I have an IBM removable cdrom device which I'm trying to use under 
FreeBSD-5.4 RELEASE. I connect it on the USB ports on my ThinkPad X40, insert a cdrom (neil young) but I cannot mount it:

"mount -t cd9660 /dev/cd0 /mnt/cdrom" yields: 

cd9660: /dev/cd0: Device not configured.

A "dmesg" then yields:

umass0: GENERIC CDRCB04, rev 2.00/0.00, addr 2
cd0 at umass-sim0 bus 0 target 0 lun 0
cd0: <IBM CDRW/DVD UJDB753 1.00> Removable CD-ROM SCSI-0 device

I have: 

device cd
device pass
device atapicam
device atapicd
device scbus
device ata

compiled into my kernel. I'm stuck. Grateful for any help/hints 
on what to try next.
