To find out which version you have, open the Device Manager by right-clicking My Computer and choosing Properties (or with Windows key + Pause/Break on the keyboard). Click the Hardware tab and then click the Device Manager. Scroll down until you locate the Universal Serial Bus controllers and expand the list of controllers. If you have a USB 2.0 controller in your computer, the word Enhanced will be listed somewhere in one of those names.
