Just to give an update, Wacom support is being worked on, either this or the next release you can beta test the new tablet (and touch) modes in MouseMux. Stay tuned :)

I just found this open source tablet drivers. It might be useful. https://github.com/OpenTabletDriver/OpenTabletDriver

It would be really awesome when someone draws on the tablet if other can keep using the computer for other purposes. I hope it will support both display and non displat tablets. And not just wacom also huion, xp-pen etc. Thanks a lot.

Yeah better support is planned!

I have installed the drivers, but wacom tablets still don't work
