Touchscreen detected, enabled, but no events

Hello everyone, I had a touchscreen that used to work on Arch (last known working is a couple of months ago though) and now it isn't.

I have tried using both evdev and libinput drivers, and both detect the device and configure a bunch of properties but it doesn't work on either. Touching the screen does nothing (including in xev and libinput-debug-events) and I've event tried watching /dev/input/event11 and I get nothing no matter what I do to the touchscreen (as a contrast the device for my touchpad dumps a bunch of stuff when I touch it). I've also tried under both Wayland and X11.

I wonder if anyone has have ideas or suggestions on why this might not be working or other things to try.

Re: Touchscreen detected, enabled, but no events

I did some more digging and found that even cat /dev/input/event1 doesn't create any output when I touch the screen which seems suspicious.
