How to mount a CD ROM from a USB CD ROM drive on Ubuntu 10.04.3 server

I am trying to mount the installation CD rom drive using a USB CD ROM drive on Ubuntu 10.4.3 server to extract additional packages (since I do not have internet active on the server). I plugged the CD rom drive and inserted the CD and I could not find any auto mounting happening. I could not figure out what would be the device name to manually mount. Looks like it is not /dev/sr0. Any guidance on mounting a CD on Ubuntu server is appreciated.

EDIT Based on the answer from Christopher, here is more information,

/0/1 scsi6 storage
/0/1/0.0.0 /dev/cdrom disk DVD RW AD-7560S
/0/1/0.0.0/0 /dev/cdrom disk 

So I guess the device name would be /dev/cdrom and I should be able to mount it with the following command

sudo mount /dev/cdrom /mnt

I get the following error.

mount: /dev/sr0: unknown device

However I can automount the CD in my Ubuntu 10.10 Desktop edition.

So please confirm I am recognising the correct /dev/<dev name>

You can glean the device name with "list hardware" (lshw):

sudo lshw -short

Output something like this:

H/W path Device Class Description
==========================================================
/0/100/1f.2/0 /dev/cdrom disk DVD+-RW GSA-H31L
/0/100/1f.2/1 /dev/sda disk 750GB ST3750640AS

Or maybe pipe to less if there is too much output:

sudo lshw -short | less

On Ubuntu Server 12.04 LTS it is as easy as:

$ sudo mount /dev/sr0 /media/cdrom

To unmount, type:

$ sudo umount /media/cdrom

TRY

 sudo su mount /dev/scd0 /mnt/{custom-name} -t iso9660 mount /dev/scd0 /mnt/{custom-name} -t udf

OR

mount /dev/sr0 /mnt/{custom-name} -t udf
mount /dev/sr0 /mnt/{custom-name} -t iso9660

To Check

ls -l /dev/{cd,dvd}*

Output

lrwxrwxrwx 1 root root 3 2012-01-29 16:58 /dev/cdrom -> sr0
lrwxrwxrwx 1 root root 3 2012-01-29 16:58 /dev/cdrw -> sr0
lrwxrwxrwx 1 root root 3 2012-01-29 16:58 /dev/dvd -> sr0
lrwxrwxrwx 1 root root 3 2012-01-29 16:58 /dev/dvdrw -> sr0

Type blkid to see a list of devices attached to your computer.

then type:

$ mount /dev/sdc1 cdrom

change sdc1 to the name of your usb stick as listed in blkid. e.g. sdc0, sdc2, etc
