FIX: https://github.com/rohitpid/Linux-Magic-Trackpad-2-Driver

installed the driver from git & reboot
blueman showing the apple magic mouse now & paired the device
mouse pointer is extreme sensitive, settings need low speed

To make it work after a reboot, i had to 'trust' the apple magic mouse 2
in blueman to make it recognized automatic after reboot

Please integrate this fix in the kernel so also apple & its devices get a smooth experience

every reboot the apple magic mouse 2 has to click a few times on desktop
to get blueman recognize the mouse, after that the blueman indicator
lights up connected

Driver is in v4.20 according ot [1] - the site also documents some user-space configuration options.
