Long Shot! M1 Mac mini + ABD Wacom ArtPad II via Griffin iMate!?!

As in the title… This powers up, the tablet picks up the proximity of the pen. You can draw with the pen on the tablet. There is no pressure control. The eraser end acts the same as the pen tip. I have tried USB Overdrive but this does nothing as far as I can see.

Toggle switch on pen is broken unfortunately. Would be good to get basic pen pressure & eraser working in Photoshop.

Am I just wasting my time?
