I ran into a problem with my new(refurbished) Z820. I'm using a wireless Logictech mouse, but whenever I plug any kind of storage device into any USB port, the mouse stops working. I've tried moving the receiver to all the other USB ports, but get the same malfunction. A corded USB mouse works just fine... The only way I've managed to get the receiver to work is to plug it into a hub. I know this makes it a non-issue, but I've never had this problem with any other computer.
Any ideas?
Thanks;
