I'm having the same problem with my new Hp laptop operating Win 7. My USB ports are not always recognized. I have to unplug what I'm using and reconnect my mouse just to get it to work. I'm not liking this at all. Two USB ports are behaving this way. Sorry I can't help you but I got up early to work on this problem today.
