Check the different layers of the problem:

CPU: login via SSH and make sure things are running.

USB protocol: use wireshark to see if the keyboard event packets are
reaching the device.

Linux input layer: use input-events from input-utils to monitor events

evdev Linux layer: use libevdev-tools or evemu-tools to monitor events

libinput Wayland/Xorg layer: use libinput-debug-events from
libinput-tools to monitor events

Xorg layer: use xev to monitor events
