The G522 exposes AdvancedParaEQ (0x020D), a different EQ feature than the PRO X 2's OnboardEQ (0x0636). Key differences: - 3-byte-per-band wire format ([freq_hi, freq_lo, gain]) vs 0x0636's 4-byte-per-band ([freq_hi, freq_lo, gain, Q]) - Device handles biquad coefficient computation — no host-side DSP math - Has explicit direction (playback/capture), multiple preset slots with getActiveEQ/setActiveEQ for switching, preset friendly names Adds new advanced_para_eq.py module with getInfos, getActiveEQ, and getCustomEQ helpers (function 0, 3, 1 respectively). Re-exported from hidpp20.py following the onboard_eq.py pattern. HeadsetAdvancedEQ setting displays the currently-active playback EQ using the same RangeFieldSetting + PackedRangeValidator UI pattern as HeadsetOnboardEQ, so the graphic EQ widget looks the same. **Writes are intentionally disabled for now** — prepare_write returns None and write() logs "read-only mode" without sending anything. This lets us verify the wire format matches the protocol doc against real hardware before risking a write that could misconfigure the DSP. Once read output is confirmed sensible, we'll wire up setCustomEQ (function 2) to enable writes. |

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.
