Webcam not available on wake

Motherboard: Gigabyte Z370P D3

Bluetooth/WiFi: Fenvi T919 (BCM94360CD)

Webcam: Logitech HD Pro C920

I'm running OpenCore 0.7.3 and Big Sur 11.6. All works great and I always sleep/wake the system (I rarely shutdown or restart), but about 50% of the time I have to unplug/plug the webcam after a wake because the camera is not present. All other USB devices work well after wake. What I've done to try to solve it, but has not changed the behaviour:

  • Tried other USB ports (USB2.0 or 3.0)
  • Created an USB map: https://Dortania.github.io/OpenCore-Post-Install/usb/intel-mapping/intel.html
  • Added SSDT-USBX (I'm using MacPro7.1) https://Dortania.github.io/OpenCore-Post-Install/usb/misc/power.html
  • Running on Secure Boot - Full Security: https://Dortania.github.io/OpenCore-Post-Install/universal/security/applesecureboot.html#apecid

Not sure if that last thing is worth mentioning, but it is the last thing I changed to the system to make Apple Watch Unlock working again (which always was buggy after an update).
