We did not address USB touchscreen support in the updated HID driver,
but disabled absolute motion handling for now. I do not have a Wacom
device at hand but my ELAN touchscreen reports BTN_LEFT press/release
on touch and logs dropped events.

  Dropping unsupported Event[1/2] device=HID 04f3:2269 Touchscreen type=ABS code=X value=2212

For some reason, the Linux driver code seems to interpret your Wacom
events differently and confuses the input handling. You may have a
look at it with the event filter <log> feature.

1. Copy /config/managed/event_filter to /config/
2. Find line <input name="usb"/> in /config/event_filter
3. Change to <log prefix="USB "><input name="usb"/></log>
4. Examine /report/log for the reported input events
