Cool. I've attached the patch I think that is needed. This is
against Linus' git that was rebased at some random time in last month
Originally, I was going to give you a patch against input-wacom but it
looks like that is different compared to upstream for graphire.
Specifically, it is correctly setting MSC_SERIAL when switching over
That means input-wacom may be working with graphire4. input-wacom is
not ever sending BTN_TOOL_FINGER for some reason so if its not working
then thats probably only change needed (add it back in to match
