Hi Peter,
First, sorry for my English.
I am not a C++ developer buy I have tried to do the patch.
The following works for me:

I also noticed that is necessary to patch linux-wacom-0.8.8-8 udev
rules or X11 does not detect the device. This is the patch:

I am a linux adavanced user but i am no a developer so I can only help
you with testing if you need.
