Mice behind an ASUS Omni receiver all enumerate with the same usb id
(0b05:1ace), so the regular bus:vid:pid DeviceMatch cannot tell models
apart. Identify the model during probe instead:
- asus-rog-omni-receiver.device is a minimal bootstrap file that only
declares Quirks=OMNI_RECEIVER, so the asus driver gets probed on the
receiver's hidraw nodes
- the probe queries the serial number signature (03 12 12 02) and
matches its prefix against the OmniSignature field of the .device
files, then re-resolves the device data for the identified usb id
- an unknown signature fails the probe with -ENODEV, which also drops
the receiver's keyboard and media control nodes
The Strix Impact III family answers with data two bytes earlier than the
original protocol (code plus params echo instead of code plus pad), so
two quirks cover the new layouts:
- LED_V2: per-zone LED responses with data at offset 4, brightness in
0-100
- SETTINGS_V2: settings and DPI responses with data at offset 4,
rate/debounce/snapping as single bytes
Also write DPI values with two bytes so presets above 12850 dpi work.
Verified on a ROG Strix Impact III Wireless: identification on hidraw4,
all 5 profiles with 8 buttons, 1 LED and DPI presets 400/800/1600/3200,
report rate 1000 Hz, debounce 12 ms, LED brightness 127 (50%). Writes
round-trip and survive a ratbagd restart.
f9d1574 enabled this for the G502 X PLUS, which is the RGB variant.
I can confirm the normal G502 X Wireless has this quirk. I do not
have a base model G502 X, but comments on issue #1606 as well as logic
suggest it very likely does unless proven otherwise.
The G502 X PLUS reports a 1-indexed active profile, so without
INDEX_OFFSET libratbag targets the wrong profile and DPI/button changes
never reach the device (the mouse boots on its first profile, reported
as index 1). It also needs the existing G502X_PLUS LED quirk, so list
both now that hidpp20 supports multiple quirks.
Verified on hardware (usb:046d:4099 via the Lightspeed receiver, Linux
7.x): the device reports active profile index 1, INDEX_OFFSET maps it to
0, and the LED still reads correctly via the G502X_PLUS slot.
* Added Quirk for G502 offset to resolve incorrect active profile being applied. Testing on G502- Hero Wireless. May be worth adding handling for multiple quirks.
* Added quirk in device files to correct offset for G502 Hero, G502-Proteus Spectrum, and G604.
* Refactored G502 Offset Quirk naming to be more broadly applicable as index offset.
* Correct typo in g502-proteus spectrum quirk value.
