HAILUCK touchpad seen as mouse and related issues
The touchpad on my "Positivo 2 em 1 Q432A" (motherboard CHT12CP, kernel 5.2.9, libinput 1.14.0) is seen as "HAILUCK CO.,LTD USB KEYBOARD Mouse", which causes/stops me from solving these issues:
*The pointer moves a few pixels after the finger stops if it's still on the touchpad;
*2 finger scrolls need more movement than it should to start and pinch-to-zoom active makes it worse;
*2 finger tap reports mouse button 3 and 3 finger tap reports "left alt" + "s";
*Sliding to the inside of the touchpad reports "left alt" + something;
The lower parts of my touchpad are actually clickable, though it doesn't look like it, and tap-to-click is active, but it doesn't appear as an option. In the libinput recording below, the sequence is: scroll up, down, left, right; pinch-to-zoom in, out; 3 twofinger taps, 3 threefinger taps; moving around. If there's anything else I can do, just tell me and I'll do it. Thank you very much.
