Can't locate my WD My Book 1130 in my Windows Vista

Just as an aside,

When I plug this device into my LAPTOP (seperate computer), it immediately prompts a “Driver Software Installation” Screen.

It says Ready to Use the Storage Device, and Ready To Use the WD My Book 1130 USB Device, and searches for a Windows update for the “WD SES Device USB Device”.

Why is this able to work so quickly on my laptop and not even make a peep on my Original CPU Desktop?

Other external drives work fine on my Desktop, no matter which USB port I put them into.  Yet the WD My Book 1130 won’t even budge the Desktop?

Might have putting this device in a seperate USB hub have totally messed things up?
