Huion Kamvas 16 (2021) bottom button not functional after update

Hello.

I have a drawing tablet with 10 buttons and the bottom one stopped working. Fedora seems to not register it being pressed at all. The overlay that is used for rebinding those buttons still shows it there, but nothing happens when I press it.

I tested the tablet under Windows 11 with the official Huion driver and the button works fine; there is no issue with the hardware.

It used to function correctly a few updates ago, but I’m not sure when exactly.

I am using Fedora Silverblue 43 and the tablet is Huion Kamvas 16 (2021) [GS1562].
