April 2000 was the release of 2.0 but adoption was another matter. I bought a new laptop early 2003 that had USB 1.1 ports. I've seen others since. You can still find packages for new USB devices marked "USB 2.0 compatible." That doesn't mean High Speed. One USB 2.0 requirement is that it work with USB 1.1 devices so "USB 2.0 compatible" is a sham. There were bazillions of low/full speed controllers made and the economy meant they did anything they could to dump them. Look for High Speed USB if you want to be sure.

For your system open up Device Manager & scroll down to the USB controller. (you may have more than one) Look for any indication of USB 2.0 or High Speed either in a controller or root hub.

Does he do any video? You might be able to talk him into a FireWire/1394 card for that camcorder he's buying.

Anyway, give it a shot. It'll work great, work slow, or just not work. It doesn't draw enough power to hurt anything.
