[Renate]

Well, there is so much wackiness going on with this descriptor I wouldn't be surprised if something kicked it out.

On the consumer controls, there are 13 bits (+3 bits padding) defined for 5 controls.

The X and Y coordinates are 12 bit but they each translate to 12.05 cubic inches.

And then there is the question of where they are even poking.
If you don't set Physical Minimum/Maximum then an X of 4095 means the right edge independent of screen size.
With it set as it is it means 12.05 cubic inches which you might interpret (wrongly) as 12.05 (linear) inches.
Depending on interpretation this might mean off the screen or clipped to the right edge.
But we don't know where it's poking anyway.

Finally, the Logical Collection on the Digitizer report seems odd.

Also, this is set up for multi-touch.
