Do I have USB 2.0 on my Windows XP computer?

How you can tell if you have 2.0 on your computer, and why it matters:

If you plug a USB 2.0 device into a USB 1.1 port, Windows XP will display a warning message indicating that it will drop back to the slower data transfer speed. (USB 2.0 clocks in with a data transfer speed of 480 Mbits/second compared to USB 1.1′s 12 Mbits/second.)

1. Right click on “My Computer” and select “Properties.”
2. Select the Hardware tab and click the Device Manager button.
3. When Device Manager appears, click the + sign next to the Universal Serial Bus Controllers branch.

If you see an entry containing the words “Enhanced USB Controller”, then the system has a USB 2.0 controller. If you see an entry containing the words “USB Controller”, the system has a USB 1.1 controller.

Note: This tip applies to both Windows XP Home and Professional editions.
