Maybe here is some mis-understanding,  the mouse mode here doesn't mean we use psmouse-base.c for cs19 (bare ps/2 mouse), we plan to use trackpoint.c to drive this HW, so this trackpoint has all features a trackpoint should have.

Just make sure that touchapad input device is not registered when this ALPS_ONLY_TRACKSTICK flag is set. So userspace would not see any fake/unavailable touchpad input device. > >> Xiaoxiao.Liu > -- > Pali Rohár > pali.rohar@gmail.com
