* Add Centurion transport and PRO X 2 LIGHTSPEED headset support
Adds support for the Logitech PRO X 2 LIGHTSPEED Gaming Headset (PID 0x0AF7)
which uses the Centurion transport protocol (report ID 0x51 on USB usage page
0xFFA0) instead of standard HID++ report IDs.
Changes:
- HID enumeration: detect Centurion devices via report descriptor parsing
(usage page 0xFFA0, report ID 0x51, 63-byte frames)
- Centurion transport: wrap/unwrap HID++ 2.0 frames in Centurion framing
for write, read, and ping operations
- Feature discovery: enumerate features individually on Centurion devices
(different response format: [remaining_count, feat_hi, feat_lo])
- Device descriptor for PRO X 2 LIGHTSPEED Gaming Headset
- New feature enum entries for Centurion-era headset features (0x06xx)
- CenturionRawRW class for write-only headset settings controlled via
raw Centurion commands reverse-engineered from HeadsetControl
- HeadsetSidetone setting (0-100 range, persisted locally)
Known limitations:
- Only sidetone control is implemented; other features need RE work
- Settings are write-only (no read-back from device)
- Headset features (0x06xx) not discoverable via IRoot; registered manually
* Remove static PRO X 2 descriptor; fully probe Centurion devices at runtime
Replace the hardcoded descriptor entry with dynamic discovery of all device
properties via the Centurion protocol. The headset name, kind, serial,
firmware, and battery are now probed at runtime — matching how the device
actually presents itself rather than relying on static data.
Key changes:
- Discover sub-device features via CentPPBridge and route requests through
the bridge automatically
- Infer device kind from feature IDs (0x06xx = headset) for both wireless
and direct USB connections
- Read device name from USB product string with protocol probe fallback
- Parse bridge error responses (sub_feat_idx=0xFF) instead of timing out
- Handle unknown HID++ error codes gracefully in base.py
- Fix firmware deduplication for Centurion parent devices
- Prefer sub-device serial/firmware over parent (non-printable) values
- Add Centurion-aware display in solaar show with parent/sub-device sections
- Support both wireless (0AF7 dongle) and direct USB (0AF8) connections
* Display Centurion dongle as receiver with headset as child device
- Add CenturionReceiver class that provides the Receiver UI interface so
the dongle appears as a parent with the headset indented underneath,
matching how Lightspeed/Unifying receivers display
- Independently probe dongle features via feature_request() on the
CenturionReceiver, separate from headset features via bridge
- Fix bridge notification dispatch: remove incorrect sub_cpl=0xFF filter
that was silently dropping all battery and other notifications
- Fix battery status decoding: charging status is at byte 2 (not byte 1)
of the CENTURION_BATTERY_SOC response
- Detect wired vs wireless by checking for CentPPBridge in discovered
features; wired headsets fall back to standalone Device
- Name the dongle "Centurion Receiver" to distinguish from the headset
- Filter unprintable dongle serial (control characters 0x14-0x1F)
- Update CLI show output with proper receiver/child hierarchy and spacing
* Fix headset setting validators and code formatting
- Add signed int8 support to RangeValidator for HeadsetMicGain (0x0611)
- Make HeadsetSidetone version-aware: v1 uses 2-byte skip, v2+ uses
3-byte skip with 0xFF separator per protocol spec
- Fix ruff formatting in device.py, listener.py, udev_impl.py
- Update CenturionReceiver test for renamed receiver
* Use ConnectionStateChangedEvent for headset online/offline detection
Replace ad-hoc heuristics with proper bridge event function dispatch:
- Function 0 (ConnectionStateChangedEvent): parse sub-device list length
to determine connect (len>0) vs disconnect (len=0)
- Function 1 (MessageEvent): fallback online detection if headset sends
a message while marked offline (handles cold-start power-on)
Remove CPL sub_id>=0x80 fallback in listener that misidentified HID++
error replies as disconnect events. Skip HID++ 1.0
set_configuration_pending_flags for CenturionReceiver (not supported).
Also adds OnboardEQ (0x0636) support, bridge multi-fragment sends,
bridge-based headset ping probe, and CLI offline display.
* Update PRO X 2 LIGHTSPEED device doc with current solaar show output
* Fix Centurion protocol version display (1.16 not 2.6)
The HID++ ping math (major + minor/10.0) produced a bogus "2.6" for
Centurion devices whose ProtocolCapabilities returns major=1, minor=0x10.
Store the raw (major, minor) bytes from the ping response and display
them correctly as "Centurion 1.16" in both CLI and GUI.
* Add OnboardEQ (0x0636) support for Centurion headsets
Implement host-computed biquad EQ coefficient generation and multi-fragment
bridge writes for the PRO X 2 LIGHTSPEED headset's 5-band parametric EQ.
The coefficient algorithm uses standard Audio EQ Cookbook peaking EQ formulas
with a simplified rescale normalization (max_b0 × 1.19 headroom). This is our
own implementation — not an exact replica of LGHUB's ~350-line per-band cascade
normalization — but it produces functionally correct results. The DSP
compensates via the rescale factor, and the EQ changes are audible and working
on real hardware.
Wire format verified against 38 LGHUB pcap writes:
- 4-byte LE section headers, LE uint16 coefficient words
- Mixed Q1.31/Q2.30 fixed-point with 24-bit precision
- Only b-coefficients divided by rescale; a-coefficients unchanged
- Two sections: 48kHz playback + 16kHz mic
- No trailing padding, no extra words between sections
Changes:
- base.py: Add flags parameter to write_centurion_cpl() for multi-fragment CPL
- device.py: Rewrite multi-fragment bridge send — proper CPL fragmentation with
fragment 0 carrying bridge prefix/hdr and continuations carrying raw sub_msg,
all fragments sent back-to-back without intermediate ACKs
- hidpp20.py: Replace placeholder coefficient code with full biquad math,
mixed Q-format quantization, rescale normalization, and dual-section output
- settings_templates.py: Persist EQ to slot 0x80 after writing to slot 0x00
so settings survive power cycle
- tests: Update expected SetEQParameters payloads for new coefficient format
* Extract Centurion protocol into separate modules
Move CenturionReceiver class, factory function, and Centurion protocol
queries (firmware, serial, hardware info, battery, name) from device.py
and hidpp20.py into new centurion.py module. Move OnboardEQ biquad math
and payload builders from hidpp20.py into new onboard_eq.py module.
Move _read_usb_product_string() to common.py to avoid circular imports.
Re-exports preserve backward compatibility for all existing callers.
* Add vertical graphic EQ slider widget for headset equalizer
Replace horizontal slider rows with a traditional graphic EQ layout
using vertical sliders side-by-side, with dB value display and
frequency labels per band.
* Fix device online state clobbered by debug ping in _status_changed
The INFO-level logging guard in _status_changed() called device.ping()
before logging, purely to show accurate online status. But ping() has
side effects — it sets device.online based on the result. When a
ConnectionStateChangedEvent correctly marked a device online, the
subsequent _status_changed() callback would re-ping. If the device
wasn't ready yet (e.g. Centurion headset still booting), the ping
timed out and set online back to False, requiring 2-3 power cycles
to sync state.
Remove the unnecessary ping — the log message already reads
device.online which reflects the state set by the event handler.
* Sort feature constants by ID and add PROFILE_MANAGEMENT
Move RPM_INDICATOR/RPM_LED_PATTERN (0x807A-B) before PER_KEY_LIGHTING
(0x8080-81), sort five Centurion-era headset entries into their correct
positions by feature ID, and add missing PROFILE_MANAGEMENT = 0x8101.
* Add CenturionCoreFeature enum for colliding feature IDs
Centurion transport reuses HID++ 2.0 feature IDs 0x0000, 0x0001,
0x0003, 0x0005, 0x0007 with different meanings. Since SupportedFeature
(IntEnum) requires unique values, create a separate CenturionCoreFeature
enum and resolve_feature() helper for transport-aware lookup.
Also replace the +0x100 offset hack in FeaturesArray.inverse with a
dedicated sub_inverse dict for sub-device feature indexing.
* Fix ruff I001 import sorting in centurion.py and hidpp20.py
* Add 9 missing centurion/headset feature names
Add feature constants split out from the HID++ 2.0 names PR (#3153):
CENTURION_LED_BRIGHTNESS (0x0110), CENTURION_EU_POWER_MODE (0x0115),
CENTURION_DEVICE_BOOL_STATE (0x0116), HEADSET_ADVANCED_PARA_EQ (0x020D),
HEADSET_MIC_TEST (0x020E), HEADSET_EQ_STYLES (0x0213),
BT_HOST_INFO (0x0305), LIGHTSPEED_PAIRING (0x0309),
BT_GAMING_MODE (0x030A).
* Extract _record_ping_protocol helper so all ping paths capture Centurion version
The raw Centurion (major, minor) pickup was only in the Centurion-child
dongle branch of Device.ping(). Wired Centurion variants (e.g. PRO X 2
LIGHTSPEED 046d:0AF8) go through the generic fallback branch and never
recorded the raw version, so they displayed "Centurion 2.6" instead of
"Centurion 1.16".
Extract the protocol + centurion version recording into a helper and
call it from both branches.

The commands were probably meant to be the other way around.
And I also think there is something missing in the sentence "and then run

If you are using pipx add the `` flag.", but I was not sure.
* Add scripts to create macOS app bundle and LaunchAgent #1244
This change introduces two new helper scripts for macOS users to improve integration with the operating system.
The `create-macos-app.sh` script builds a minimal `.app` wrapper for Solaar. This allows Solaar to be treated as a standard macOS application, enabling it to request necessary permissions, such as input monitoring, and to be discoverable by the OS. The script generates the required directory structure, a wrapper executable to launch Solaar, a standard `Info.plist` file, and an application icon from the source PNG.
The `create-macos-launchagent.sh` script sets up a LaunchAgent to automatically start Solaar at login and keep it running in the background. This ensures that the Solaar process is always available for device management without requiring manual intervention from the user. The script also configures log file locations for standard output and error streams.
Together, these scripts provide a more native and user-friendly experience for Solaar on macOS.

* Fix icon in script to create macOS app bundle #1244https://github.com/pwr-Solaar/Solaar/issues/1244
* build: Remove hardcoded Homebrew path for solaar in macOS script
The `create-macos-app.sh` script previously defaulted to a hardcoded Homebrew path for the `solaar` executable. This change removes the specific path, defaulting instead to `solaar`.
This modification makes the script more flexible and robust. It allows the system's `PATH` to resolve the location of the `solaar` binary, accommodating various installation methods beyond a fixed Homebrew directory. The explicit check for the executable's existence is also removed, as the script will now rely on the command being available in the shell's environment, which is a more standard approach.
* refactor(macos): Improve solaar executable lookup in launchagent script
This change improves how the `create-macos-launchagent.sh` script locates the `solaar` executable.
Previously, the script defaulted to a hardcoded path (`/opt/homebrew/bin/solaar`) and would exit with an error if that specific file was not found and executable. This was too restrictive and failed in environments where `solaar` is installed in a different location, such as through `pipx` or in standard system paths like `/usr/local/bin`.
Now, the script defaults the `SOLAAR_PATH` to just `solaar` and uses the `command -v` utility to find the executable in the user's `PATH`. This allows the system to resolve the correct location of the `solaar` binary automatically. If the executable cannot be found in the `PATH`, the script now issues a warning instead of exiting, and proceeds to use the provided `SOLAAR_PATH` value in the generated LaunchAgent plist. This makes the script more flexible and robust for different installation methods.

This makes the script more flexible and robust for different installation methods.
* refactor: Improve Solaar path resolution in macOS helper scripts
This change improves the robustness of the macOS helper scripts by ensuring the Solaar executable is found before proceeding.
Previously, `create-macos-launchagent.sh` would only issue a warning and continue with a potentially invalid path if the `solaar` command was not found. `create-macos-app.sh` had a typo (`SOLAR_PATH`) and lacked a check altogether.
Now, both scripts (`create-macos-app.sh` and `create-macos-launchagent.sh`) will:
- Correctly check if the `solaar` executable exists in the system's `PATH`.
- Use the resolved, absolute path to the executable to avoid ambiguity.
- Exit with an error if the executable cannot be found, preventing the creation of a broken app bundle or launch agent.
* feat(macos): Relaunch app to fix tray icon and add Dock icon
This change modifies the macOS app bundle creation script to improve the application's behavior and user experience on macOS.
Previously, when Solaar was launched as a standard `.app` bundle, macOS restrictions sometimes prevented the GTK tray icon from appearing correctly. This change introduces a workaround in the wrapper script. The application now relaunches itself as a detached background process on the first launch. This new, detached process is no longer subject to the same `.app` bundle restrictions, allowing the tray icon to be created reliably.
Additionally, the `LSUIElement` key in the `Info.plist` is set to `false`. This makes Solaar a regular application with an icon in the Dock, which is the standard behavior expected by most macOS users for a graphical application.
* docs: Explain macOS Python.app Dock icon limitation
This change adds a comment to the `create-macos-app.sh` script to explain why the Solaar application may still show a Dock icon on macOS, even when it is not desired for a background utility.
On macOS, Python often runs as `Python.app`, which has its own `Info.plist` file. This built-in `Info.plist` takes precedence over the one generated for the Solaar app bundle. As a result, settings like `LSUIElement=true`, which would normally hide the Dock icon, are overridden. This comment clarifies that this behavior is a known limitation of the Python distribution on macOS and not a bug in the Solaar packaging script.
* docs: Add instructions for creating macOS launcher options
This update enhances the installation guide by including steps to set up macOS launchers for Solaar. Two options are provided:
- LaunchAgent for automatic background execution and crash recovery.
- App launcher for manual addition to Login Items.
