Ken Sanislo e06c4ce93a HeadsetAutoSleep: read-modify-write a single uint8 timer slot
HID++ 0x0108 is not a single integer: V3 carries two uint8 timer slots,
V4+ carries three. The old code decoded the response as one big-endian
integer and wrote the user's value into byte[0] with the other slots
zeroed — which the firmware rejects, so writes silently never round-tripped.

_AutoSleepRangeValidator now decodes only the user-facing slot (byte[0]
on V<3 and V4+, byte[1] on V3 per LGHUB) and builds the wire payload by
reading the current bytes and mutating only that slot. Range becomes the
real uint8 0–255 (not the arbitrary 240), and the description drops the
"minutes" claim since per-slot units are device-specific.

See ~/ghub/solaar_0x0108_autosleep_impl_guide.md for the RE notes.

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:
