Work in Linux?
As of 2021-10-16, all buttons works on linux out of the box. Linux kernel dated before 2019-05-30, the pinky button may not work.
the M-XT3DR model is NOT fully functional in Linux out of the box; the rightmost button isn't detected at any level, and “right click” comes mapped to the middle button. — user Trilkhai, 2017-02-11
The top left 2 buttons are browser back and forward.
You can remap mouse buttons in Linux using
