0x2150 thumbwheel

The horizontal thumb wheel on MX-line mice. getThumbwheelInfo reports its capabilities (resolution, native vs divertable, default direction); getThumbwheelStatus reads the current reporting mode; setThumbwheelReporting diverts the wheel so its rotation is delivered to OpenLogi as events instead of native scrolling. While diverted, the feature emits status updates carrying the rotation delta plus touch / tap flags.

OpenLogi diverts the thumb wheel to drive horizontal scroll and the ThumbwheelScrollUp / ThumbwheelScrollDown bindings, scaled by the thumb-wheel sensitivity setting.

Spec: Logitech HID++ 2.0 — x2150 thumbwheel. Used by: thumb-wheel bindings.

Full function reference coming soon.
