Have you checked to see it its visible in Disk Management?
Plug it in
Right Click on "My Computer"
Select Manage->Disk Management

and see if it shows. If it is visible but does not have a drive letter, right click on it, select "Change Drive Letter and Paths" and choose a drive letter - this is non-destructive

try these :
unplug pc from power for 30 minutes
then test
-----------------------
start>run>services.msc

look for Removable Storage Service. Is is set to Auto, and if not started, click the Start link in the top left...
In c:\windows\system32\drivers, look for usbstor.inf -  If not found, copy from another PC. If you find it, right click it and select Install
See if it rebuilds the USB support...
----------------------
 copy the USBSTOR.SYS from a working PC to the bad one. (copy the old one somewhere else first)
normally located at c:\windows\system32\drivers
----------------------
copy C:\Windows\Inf from aworking pc to the bad one.

Have you tried plugging in both USB connectors (assuming it came with two on the cable)? Sometimes one USB port especially older USB 1.0 ports do not provide enough power. Just because the drive/enclosure lights or spins up does not mean it is getting enough power to function.

You'll have a card reader or something and your computer will be assigning a drive letter already assisgned. Go with KCTS's suggestion 1st, it'll take 5mins tops for even a novice and will solve the problem 90% of the time.
