Detect Resolution Multiplier in attached mouse's HID descriptor and normalize wheel/pan values to standard notch units before forwarding. Prevents scrolling being ~16× too fast with hi-res scroll devices (e.g. Endgame trackball).

Passing real highres scroll would be better, but much more effort. This helps until somebody wants to do it.
