TROUBLESHOOTING
If the Wacom Tablet driver failed to load properly, first perform the recommended action in the error 
message on your screen.  If that does not solve the problem, perform the following tests for your tablet or 
tool(s) to determine whether the source of the problem is the tablet hardware or a software conflict.
TESTING USB TABLETS
Make sure your computer is turned on, the operating system has finished loading, and Graphire2 is 
properly connected to an active USB port.  Then try the following tests:
1.
Check power to the tablet.
  The tablet’s orange status LED will light whenever Graphire2 is properly 
connected and your computer has registered it as a USB device.  If the LED is on, continue with step 2.
If the LED is off:
Make sure the USB cable is securely connected to an active USB port.
If you are connecting the tablet to a USB hub (or hub device such as a keyboard with USB ports), 
be sure the USB hub is properly connected to your computer and is active.
Connect Graphire2 into a different USB port or try connecting to the USB port on another 
computer.
If the tablet’s status LED does not illuminate after your computer is on and has finished booting up, 
your USB port may be inactive.   See
