It's definitely USB2. I have one and you don't get the "this drive could operate faster message". However, you are right that it won't "drive" an external hard drive (tried), and therefore we can assume not a DVD writer either. Not sure about a webcam.

Excellent deal at this price then. Most USB hubs I've used/seen which don't require an independent power source and are part of a larger device (i.e. desktop monitor, gadgets like this) have tended to be the old type USB with slower speeds. Especially at this price.
You say you have this fan yourself?, can I ask how loud it is?.
