Troubleshooting for Macintosh
Condition
E v e n w h e n c o n n e c t e d t o
t h e U S B p o r t , t h e p e n i s
inoperable.
The product always reverts to
mouse mode and the pressure
function cannot be used.
What to Do
-Check the connection of the USB connector. Connect directly to the
computer’s USB port.
-If equipped with a USB card, the system software has probably not been
installed properly.
-If you have any other high-speed, high-power USB peripherals, connect
these and check and see whether they operate properly or not. If these
other units operate properly, this would seem to indicate that the tablet is
defective.
The tablet driver may not be properly installed. Try reinstalling it.
