Module session 

Long-running device sessions.

Each session holds one HID++ channel open for one device, diverts the controls it needs, streams events until stopped, and restores the device’s native behavior on the way out: gesture and keyboard capture control presses for the agent to dispatch, host_switch follows a keyboard’s host keys to switch its linked pointing devices. A restore that cannot finish leaves any of them as a restore::PendingRestore token.

Modules

gesture

Live control capture for one device: divert the device’s gesture sources (DPI/ModeShift, the MX dedicated gesture button and/or the MX Master 4 haptic panel), and the thumb wheel over HID++ and turn their events into CapturedInput the GUI can dispatch.

host_switch

Keyboard-initiated host-switch synchronization.

keyboard

Live key capture for one keyboard: divert the bound 0x1b04 controls and turn their physical edges into CapturedInput the agent can dispatch.

restore

Firmware ownership that outlives the session which took it.
