Ken Sanislo 7c73c88867 AdvancedParaEQ: correct V2 band-stride and header length
The V2 parser was using stride [filter, gain_hi, gain_lo, freq_hi,
freq_lo] with a 3-byte header. Pcap traces of LGHUB ↔ G522 LIGHTSPEED
show the actual wire is [freq_hi, freq_lo, filter, gain_hi, gain_lo]
with a 1-byte header (just dir_echo; the centurion bridge omits the
slot_echo the protocol spec describes for getCustomEQ).

With the old stride, slot 0's 10-band response on G522 parsed as 9
bands: the highest band (19 kHz, +2.75 dB on the active preset) was
silently swallowed because byte alignment landed on what looked like a
freq=0 end-sentinel. The displayed bands were also shifted — 20 Hz was
missing from the front because the parser started one full band late.

See ~/ghub/solaar_0x020D_slot_investigation.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:
