Thanks for testing it. The keyboard is expected to not be working because the
current hid-asus-fte simply ignores everything but the multitouch touchpad
reports.

Could you attach a hid-recorder output of the touch events once hid-asus-fte is
in use? This way, we will be able to see if the device switches to multitouch
or stick to single touch.

That's expected for bluetooth devices.

Seems like the driver binds correctly.
