Controller Not Showing Devices (USBDeview Fix) Updated
Section titled “Controller Not Showing Devices (USBDeview Fix) Updated”If your controller appears in SignalRGB but devices connected to it are not detected or the controller is not recognized at all, a USB device conflict may be preventing Windows from enumerating it correctly. Use USBDeview to clear stale USB entries:
- Download USBDeview from NirSoft (free utility).
- Run USBDeview as administrator.
- Find your controller in the list. Look for entries related to your controller’s name or USB VID/PID.
- Right-click the entry and select Uninstall Selected Devices.
- Unplug the controller from USB, wait 10 seconds, then plug it back in.
- Windows reinstalls the driver. Open SignalRGB and check if the controller now appears correctly.
If the controller still does not appear, try a different USB port or use an internal USB hub to avoid sharing bandwidth with other devices.
