Help -- for Wacom Intuos GD users on windows IE - XP users: I bought an used Wacom tablet on e-bay and an ADB to USB. I hooked it up by slapping the wacom male to the ADB to USB and shot that into the USB 2.0 hub. The Wacom reacts with a green indicator light although the pen won't work. I've installed the download software and can not get the Wacom pen / device to work. Any idea's??? Many, many thanks...
