[DIGImend-users] Huion H610 maximum pressure events

[Dan R. <ade...@gm...>]

Hi Everyone,
    I've had my Huion H610 for almost a year now, and it has exhibited the
same behavior the entire time I've owned it, across multiple drivers
versions, and across changing the pen "tip".

Occasionally when the pen is not touching the tablet, but in proximity, I
receive events for full pressure (2047), sometimes in rapid succession.
Pressure will spike from 0 to 2047 and back. When drawing in Gimp it sort
of looked like the tool was "dripping", as max pressure events made large
marks on the image. I instrumented hid-huion with a large amount of logging
and observed that these events existed at the kernel level, and I was able
to mitigate (or eliminate?) them by detecting instantaneous transitions
between minimum and maximum pressure and throwing out these events. This
was admittedly a pretty dirty hack, and I haven't ported it over to driver
v5 yet.

*Has anyone else with a H610 noticed this problem?*

It seems there's some possibility it could be a hardware OR software issue,
so I'm curious if anyone else has noticed this.

Thanks,
Dan
