Look in device manager for the USB controller and see if it says USB 2.0 or enhanced.

when was the machine purchased ? I am sure if it has been purchased before April 2001 it CANNOT have USB 2.0

Newer machines also doesnot necessarily have USB 2.0..

CLick on the + sign to the left of Universal Serial Bus Controller
If you see Enhanced USB HOST controller or anything with Enhanced , you are sure to have USB 2.0

(well same what Callandor has told...)

mcrmg,

But there are certain desktpo where you can have both USB 2.0 and USB 1.1 and that can be decided what other sub-dvisions that you see by clicking on + near to Universal Serial Bus Controller.
