Touchpad not working on FW 13. How to check if Linux finds the device?

Framework Laptop 13 Linux
1

Which Linux distro are you using?
Ubuntu 22.04

Which Framework Laptop 13 model are you using? AMD Ryzen™ 7040 Series

My touchpad was working fine until one day it stopped working. I tried unplugging and plugging back in all connectors, and it didn’t help.
What should I expect to see in lsusb or in other places under proc in order to check if the kernel finds the device or not?

Looks like the touchpad is connected over i2c. My libinput devices:

sudo libinput list-devices

Thank you!
Indeed I don’t have these in libinput, and the messages you posted used to show up in the logs but no more…
