Ken Sanislo e8af8b08c2 HeadsetSidetone: scale UI percent to the device's gain-step grid
The 0x0604 wire "level" is a gain-step index 0..N-1, not a 0-100
percent. G HUB reads the step count N from getSidetoneLevelSettings
(function 2) and scales: level = (N-1)*pct/100. Solaar wrote the raw
percent, which only matches when N == 101 — so V2 headsets reporting a
smaller N (G522: N=10) got out-of-range step writes the firmware
silently ACK'd without applying.

Read func 2 at build time, take reply byte 2 as N (default 101 when
the call is absent — V1 — or the reply is unusable). The validator now
maps the 0-100 UI percent to/from the wire step index and clamps
writes to N-1. V1 devices (e.g. PRO X 2) keep N=101, which makes the
scaling an exact identity — their wire traffic is unchanged. The raw
func-2 reply is still logged at debug level for a future G HUB
setpoint correlation.

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.

  • configuring device settings
  • custom button configuration
  • running rules in response to special messages from devices

For more information see the main Solaar documentation page. -
