When you plug the external USB drive in you should see messages like these from 'dmesg'
usb 1-2.3: USB disconnect, address 8
usb 1-2.3: new high speed USB device using ehci_hcd and address 9
scsi6 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 9
usb-storage: waiting for device to settle before scanning
Vendor: LITE-ON Model: DVDRW SHW-1635S Rev: YS0J?
Type: CD-ROM ANSI SCSI revision: 00
sr0: scsi3-mmc drive: 48x/48x writer cd/rw xa/form2 cdda tray
Attached scsi CD-ROM sr0 at scsi6, channel 0, id 0, lun 0
usb-storage: device scan complete
If you don't see the 'Vendor' stuff there's nothing that can be done. Your drive/enclusure combination do not work together. This isn't a Linux issue but a Firmware/BIOS issue between the drive and enclosure. Try another drive/enclosure combination, or give up.
If you seen the 'Vendor' stuff and the message regarding 'Attached scsi CD-ROM sr0' then you may be in luck! Linux recognised the drive and has attached it.
Put a CDROM or DVDROM in the drive and attempt to mount it.
mount -t iso9660 -o ro /dev/sr0 /mnt
(you may have another device name. I have seen /dev/scd0)
No returned errors will mean that you have successfully mounted the CDROM under /mnt.
Any error about missing block device will mean that you need to install and load some kernel modules.
