Hi Maxim,

I'll give a summary in English for others.

Maxim has tried the official Huion driver and found that cursor only moves in
a small rectangle at the top left of the screen. Wacdump has determined its
pressure range to be 0-1024, whereas the actual reported pressure goes up to
2047. He doesn't remember the specific reported resolution, but remembers that
it was incorrect. He noticed that all the buttons work (I assume he means
the ones on the frame). He comments that the tablet works better without the
official driver (I assume that Martin's driver works instead in that case),
with the exception that buttons don't work.

I'm not sure which kernel driver he means, but he says that it works well with
wizardpen and wacom drivers, but not with evdev. Maxim, could you please
clarify this?

On my part I can say that I anticipated the "small rectangle" problem, but
wasn't sure if the driver could be that broken. This happens because the
driver specifies coordinate range much bigger than actually reported. This is
also the reason for incorrectly reported resolution. The pressure range is set
incorrectly by the driver as well.

The buttons don't work with the current kernel driver because Huion 580 which
we targeted doesn't use additional interfaces used by Huion H610 for button
reports, and we haven't anticipated Huion reusing product IDs in other tablet
models. I plan to handle that in the new version.

Maxim, could you please run the new version of huion-probe with your tablet
and send me the results? You can use one of the binary packages:
https://github.com/DIGImend/huion-tools/releases/download/v2/huion-tools_2_amd64.deb
or
https://github.com/DIGImend/huion-tools/releases/download/v2/huion-tools-2-1.fc18.x86_64.rpm

Or compile it from source:
https://github.com/DIGImend/huion-tools/releases/download/v2/huion-tools-2.tar.gz

Thank you.

Sincerely,
Nick
