USB 2.0 ports do not work

2 posts in this topic

Recommended Posts

Hello guys,

 

I've successfully installed macOS Big Sur on my PC using the vanilla installer from the official App Store and the latest OpenCore.  Everything's works out of the box, except the USB 2.0 ports.  USB 3 ports are fine though.  Any ideas on how to solve this issue?

 

My hardware specs:
- Motherboard: Gigabyte Z390 M Gaming (latest BIOS FL9)
- Processor Intel Core i7 9700K 3,6GHZ
- Memory: 64GB of Corsair Vengeance LPX 3000MHZ DDR4 RAM (2x32)
- Internal storage: 2 TB (2x1) NVMe WD_750 Black
- GPU: Gigabyte Radeon RX 590 8GB
- Connectivity: Broadcom Wi-Fi/Bluetooth combo PCI card (Fenvi 1200)

 

Thanks a million! :)

Please go to Account Settings and fill in Signature with your hardware.

 

Do you have in your EFI folder any kext called USBMap or USBPorts with the ports map of your motherboard? Do you use the kext USBInjectAll? Or maybe you don't use any kext to adjust your USB ports?
