I have a Wacom Pen Partner and since upgrading to XP, I can no longer use it. I downloaded the appropriate driver from Wacom but when installing it, it tells me I need to have it plugged into either a serial port or ubs. However, the cord that came with the tablet has neither of those connections and plugged into a mouse port. I've messed around with it this weekend and have finally given up in frustration - I have some credit left at a computer store so I think I will just opt for a new tablet. I have talked to Wacom but they were not very helpful. :) Irene
