This has been modified to work with my tablet, the Huion GT-185. Main issue was a change in the packets recieved via USB but it also has configurations meant for my laptop specifically and a bit of a left-handedness tweak
Scrollbar section was removed from the main loop because this tablet doesn't have a scrollbar
I have no current plans to maintain this, use at own risk of failure
