I have solaar (1.1.13) showing the following information for a wireless touchpad, however the touchpad is ignored by the desktop environment (Wayland on Ubuntu 22.04).
It just stopped functioning a few days ago with no clear reason.

I have had a similar issue few years ago, a few Ubuntu releases back, solved by upgrading. However I have this issue also with the latest version of solaar this time.
Of course I've already tried all the obvious things voodoo ― replacing batteries, restarting, re-pairing, using a different USB port ― several times.
What should be my next steps after the following?
diagnostic outputs from libinput:
$ libinput list-devices
Device: Logitech Wireless Touchpad
Kernel: /dev/input/event27
Group: 6
Seat: seat0, default
Size: 95x64mm
Capabilities: pointer gesture
Tap-to-click: disabled
Tap-and-drag: enabled
Tap drag lock: disabled
Left-handed: disabled
Nat.scrolling: disabled
Middle emulation: n/a
Calibration: n/a
Scroll methods: *two-finger edge
Click methods: none
Disable-w-typing: n/a
Accel profiles: flat *adaptive
Rotation: n/a
Crucially, using sudo libinput debug-events I can see that every finger motion and every button click on the touchpad do accordingly translate to a POINTER_MOTION and POINTER_BUTTON event, same as when fiddling a plain mouse connected to the same machine. Only, the plain mouse moves the cursor and makes clicks happen, whereas with the touchpad there's no effect other than its events showing up in the wayland debug trace.
