openlogi-hid

HID++ device discovery and control helpers for OpenLogi.

This crate is the OpenLogi-oriented HID layer built on top of async-hid and the workspace's vendored openlogi-hidpp protocol crate. It owns device enumeration, receiver routing, shared-channel transport setup, and a small set of typed operations used by the CLI, agent, and GUI.

Use this crate when OpenLogi needs to talk to Logitech HID++ devices through the host HID stack. Use openlogi-hidpp directly when implementing protocol-level feature support that is independent of OpenLogi's discovery and transport policy.

Public entry points include:

• enumerate for a one-shot inventory of receivers and paired devices.
• list_pairing_receivers, run_pairing, and unpair for receiver pairing.
• get_dpi, set_dpi, SmartShift, high-resolution wheel, thumbwheel, and reprogrammable-control helpers for supported HID++ features.
• set_keyboard_color / set_keyboard_color_with for solid keyboard RGB — preferring the typed ColorLedEffects (0x8070) wrapper and falling back to the PerKeyLighting (0x8080) stream.
• dump_features and dump_reprog_controls for diagnostics.

Protocol-level feature support lives in openlogi-hidpp; this crate adds the discovery, routing, fallback, and error-classification policy on top.
