Sometime last month, the lower half of my Huion KD100 simply stopped working after an update. This happened when I was still using Fedora 42. I upgraded to Fedora 43 last week thinking it would resolve the issue, but it unfortunately didn’t.
When I run
sudo libinput debug-events
And press buttons on the lower half of the device, nothing is detected.
I’ve noticed that only input from buttons 0-9 (the top ten) get detected.
