Huion gt191 missing tablet capabilities: resolution.

[kalle-ankan]

Hello

We have an HUION GT-191 that is not working.

We try to use it on Debian buster, below have I listed some output. It seems that the input driver is missing tablet capabilities: resolution. Any idea how debug it or make it working?

Hi

We got it working now you can close the bug. It was an typo. So I can confirm that Huion GT 191 works in Debian 10 (Buster).
