Ken Sanislo e5e4a4bdd0 Reassert headset colors on switch to Solaar; enable LogiVoice state toggles
HeadsetLEDControl: when switching from Device to Solaar control, the
firmware drops any previously-programmed zone colors — so after the
mode write succeeds, reassert the saved Primary + per-zone overrides
via a single zone-map write. Previously the LEDs stayed on the last
device-driven effect until the user edited a color, which made the
mode switch look broken.

LogiVoice state: SetState (fn 0x00) / GetState (fn 0x10) carry a
single boolean byte across all modules 0x0901-0x0907 (confirmed via
G HUB reverse-engineering — LGHUB only ever writes 0x00 or 0x01).
Drop the write-block in _LogiVoiceStateSetting and remove persist=
False so the per-module toggles behave like every other boolean
setting. Per-module Parameters remain read-only until each field's
wire encoding is confirmed.

Labels: "LogiVoice Noise Reduction: State (read-only)" becomes just
"LogiVoice Noise Reduction"; description updated to "Enable the
headset ... processing block." now that it's user-writable.

Solaar

Solaar is a Linux manager for many Logitech keyboards, mice, and other devices that connect wirelessly to a Unifying, Bolt, Lightspeed or Nano receiver as well as many Logitech devices that connect via a USB cable or Bluetooth. Solaar is not a device driver and responds only to special messages from devices that are otherwise ignored by the Linux input system.

Solaar supports:

  • pairing/unpairing of devices with receivers
  • configuring device settings
  • custom button configuration
  • running rules in response to special messages from devices

For more information see the main Solaar documentation page. -

Installation Packages

Up-to-date prebuilt packages are available for some Linux distros (e.g., Fedora) in their standard repositories. If a recent version of Solaar is not available from the standard repositories for your distribution, you can try one of these packages:

Solaar is available from some other repositories but may be several versions behind the current version:
