Ken Sanislo 2e07b112ff G522 bug batch from log df178225
Five fixes from analysis of the latest user log:

A. HeadsetMicMute.build() now matches device.product_id as the hex
   string ("0B18", "0B19") rather than ints. product_id is set as a
   str by hidapi_impl.f"{pid:04X}", so the int comparison was always
   False and the suppression never fired. The G522 was still being
   asked to write mic-mute on each connect and erroring out 0x0A.

B. RGB-effects probe sub-device feature dump tolerates "unknown:HHHH"
   string features. _format_feature now detects that shape explicitly
   (and renders 0xHHHH from the suffix) instead of letting int(feat)
   raise ValueError mid-iteration and abort the whole table dump.

C. HeadsetActiveEQPreset.write replaces the bare `_value = None` cache
   invalidation with a synchronous read(cached=False) so _value is a
   real dict before returning. Prevents a UI band-click crash with
   'NoneType' object is not subscriptable when a user clicks an EQ
   band before the panel re-reads after a preset switch.

D. New probe_advanced_eq_slots() iterates every advertised slot via
   getCustomEQ at build time, logs which respond, and caches a list
   of (slot, name, bands) on device._advanced_eq_working_slots. The
   HeadsetActiveEQPreset selector builds choices only from working
   slots and returns None from build() if ≤1 slot responds — G522's
   firmware advertises 16 slots but only honors slot 0, so the user
   no longer sees a 16-option dropdown they can't actually use.
   HeadsetAdvancedEQ.build now reuses the same probe (cached) rather
   than the old probe_all_presets path. The legacy alias is kept in
   the hidpp20 facade for any external callers still on it.

E. (capture only — no parse change yet) get_advanced_eq_params and
   get_advanced_eq_defaults now log raw=<hex> on success too. The
   two functions decode the same slot to wildly different bands on
   G522 (likely a different header size between getCustomEQ's reply
   and getEQDefaults's reply); raw bytes will let us pin down the
   exact framing difference and adjust the parser in a follow-up.
   Fix path will land alongside docs/features.md notes documenting
   the per-call format variation, since other 0x020D headsets may
   diverge differently from G522.

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:
