After installing my sumagraphics digitizer and calcomp driver (tweser2kxp) I am unable to configure my tablet. When I enter the "tablet" command it says "your pointing device cannot be used as a tablet".
I can see that my digitizer works to the point that the puck moves the cusror on the screen.
The error message means your driver is not being recognized as one belonging
to a tablet. AutoCAD will not fix this, you need a driver that AutoCAD can
use as a tablet, not a mouse (why it moves on screen, because Windows sees
it as a mouse driver).
