so this uses USB vendor and product ids of 056a:0081. So only thing that
makes me worry is, that all USB based Wacom tablets are blacklisted in
the hid-core.c file in the Linux kernel. Maybe there is a reason for it
and you need some crappy X-Window driver to make it work correctly.

Nothing special in here, but someone should decode the report descriptor
to see what this device expects.

You wrote something about a switch. Is there a difference in the SDP
records if you choose a different setting?
