[Device]: G502 X Lightspeed and Powerplay Mat

### Pre-flight checklist

- [x] I quit **Logi Options+** before testing.
- [x] I searched existing issues for my device.

### Device model

G502 X Lightspeed and Powerplay Mat

### Connection

Other / not sure

### What's the problem?

Device is not detected at all

### `openlogi list` output

```text
(inventory read from the running agent)
No Logitech HID++ devices or webcams found.

Notes:
- On macOS, quit Logi Options+ first — both apps fight over HID++ access.
- A Bluetooth-direct mouse (e.g. Lift, Signature) needs Input Monitoring permission: System Settings → Privacy & Security → Input Monitoring.
- hidpp 0.2 only recognises Logi Bolt receivers (PID 0xC548); other receivers (Unifying) aren't surfaced yet.
```

### `openlogi diag features` output

OS: Windows 11 26200

Start with the code paths behind `openlogi list` and `openlogi diag features`, then inspect how HID++ receiver PIDs are discovered and filtered. Reproduce with the reported LIGHTSPEED receiver PID 0xC53A and verify that the receiver, G502 X Lightspeed, and Powerplay Mat are detected instead of producing “no online HID++ devices found.”
