Description
### Pre-flight checklist
- [x] I searched [existing issues](https://github.com/AprilNEA/OpenLogi/issues?q=is%3Aissue) and this is not a duplicate.
- [x] I am on the [latest release](https://github.com/AprilNEA/OpenLogi/releases/latest) or a recent `master` build.
- [x] I quit **Logi Options+** before running OpenLogi (the two apps fight over HID++ access and only one can own a receiver at a time).
### Which part of OpenLogi?
GUI (desktop app)
### OpenLogi version
0.8.3
### Operating system
Windows
### OS version & architecture
Windows 11 Home 23H2, amd64
### Device model
MX Ergo S, Logi Bolt Receiver
### How is the device connected?
Logi Bolt receiver
### Affected area(s)
- [x] Device discovery / detection
- [ ] Button remapping
- [ ] DPI control
- [ ] SmartShift
- [ ] Per-application profiles
- [ ] Battery status
- [ ] Settings / configuration (TOML)
- [ ] Auto-update
- [ ] Menu bar / tray
- [ ] Other
### What happened?
OpenLogi is unable to detect my MX Ergo S on Windows. I've seen it detect once, and then it vanished and never again. The same device works fine on my Mac.
Logi Options+ used to be installed, but I've cmpletely uninstalled it and have rebooted several times since then.
### Steps to reproduce
Use Win11
Uninstall Logi+
Install OpenLogi
Have MX Ergo S
### Diagnostics report
```markdown
### OpenLogi Diagnostics
**App**
- OpenLogi (GUI): v0.8.3 (release)
- Agent: v0.8.3 (connected)
- IPC protocol: GUI 29 / agent 29
- Inventory: ready
- OS: Windows (x86_64)
- Locale: en-US (UI: follow system)
- Accessibility: granted · Input hook: installed
- Launch at login: yes · Menu bar: yes · Update check: on
- Running from: source build (dev)
- Config: schema 7 · 1 configured device(s) · thumbwheel 14
**Assets**
- Source: user cache · Index: loaded (210 models) · User cache: present
- Cache path: C:\Users\dfras\.local/share/openlogi\assets · Bundle assets: absent
**Devices (0)**
- No devices detected.
```
### `openlogi list` output
```text
PS C:\Users\dfras> openlogi list
(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.

```
### Logs
```shell
PS C:\Users\dfras> set OPENLOGI_LOG=debug
PS C:\Users\dfras> openlogi
(no agent reachable — reading hardware directly; macOS judges this process's Input Monitoring grant, not the agent's)

### macOS permissions (if applicable)
- [ ] OpenLogi has **Accessibility** permission (needed to remap buttons via the event tap).
- [ ] OpenLogi has **Input Monitoring** permission (needed for Bluetooth-direct devices and capture).

Research direction
Start by reproducing the issue on Windows 11 with an MX Ergo S and Logi Bolt receiver, using `openlogi list` and the debug logging shown in the report. Investigate the device-discovery path based on the receiver probe timeouts and confirm that the device is detected reliably; done means it appears in inventory and `openlogi list`.
