Pressure sensitivity no longer works for HUION graphics tablet with resent Linux kernel
Open, Needs TriagePublic


System Information
Arch Linux 4.10.2-1-ARCH
GTX 1070 with Nvidia driver

Blender Version
Broken: 2.78c , 2.78b and 2.78a

Worked: Worked before upgrading to 4.10. Works fine in 4.8.11-1-ARCH

After updating my system the pressure sensitivity from a HUION H610 no longer works. The pressure sensitivity does still work in other programs such as GIMP, MyPaint and Krita.

Other notes:
I have noticed that the input devices listed in $xinput are different concerning the Huion tablet from Linux 4.8 to 4.10

In 4.8.11-1-ARCH:
$ xinput | grep HUION
HUION TopwinT261 Pen id=14 [slave pointer (2)]
HUION TopwinT261 Mouse id=15 [slave pointer (2)]
HUION TopwinT261 Consumer Control id=16 [slave pointer (2)]
HUION TopwinT261 System Control id=17 [slave keyboard (3)]
HUION TopwinT261 Keyboard id=18 [slave keyboard (3)]

In 4.10.2-1-ARCH:
$ xinput | grep HUION
HUION TopwinT261 Pad id=10 [slave pointer (2)]
HUION TopwinT261 Consumer Control id=11 [slave pointer (2)]
HUION TopwinT261 Pen Pen (0) id=16 [slave pointer (2)]
HUION TopwinT261 Pen id=9 [slave keyboard (3)]
HUION TopwinT261 Consumer Control id=15 [slave keyboard (3)]
