Issue: The cursor does not respond to pen touch or button clicks. The tablet indicator light switches to green when pen touches tablet or buttons are clicked. You receive an error stating “A supported tablet was not found on the system” when attempting to launch the Wacom tablet software.
Unplug the unit, wait a few seconds, then plug back in.
Or, uninstall your current driver and install version 4.78. According some Wacom forums on related topics, 4.78 is the driver to use for a serial Intuos tablet on Windows XP. You can find a list of older Wacom drivers on the Wacom-Europe site. I haven’t found it on the U.S. site.
