Short description of error
Pressure sensitivity with XP-PEN Deco 01 not working in blender. In GIMP and krita, the pressure sensitivity does work.
I use tablet driver from official xp-pen website:
https://www.xp-pen.com/download/index/cid/36.html

It's not working right after the application starts.

Exact steps for others to reproduce the error

  1. Delete the cube
  2. Add UV Sphere
  3. Add subdivision surface modifier
  4. Apply subdivision surface modifier
  5. Change from object mode to sculpt mode
  6. Start sculpting with pen tablet

Also when use grease pencil

Thank you @Brecht Van Lommel (brecht)... It's now working if I didn't run xp pen tablet driver from website. But if I run the driver from xp pen tablet driver (https://www.xp-pen.com/download/index/cid/36.html), the pressure sensitivity is not working

I think this fix should work based on the xinput log, but let me know if it doesn't work in tomorrow's build.
