This is my first posting and exposure to Apple products and I am having issues with USB devices that pose no problem with my Win 10 laptops. I am using Big Sur installed on NVME drive via Open Core Legacy. I am using recommended RX 580 GPU and generic PCI USB card. All USB ports are functioning but do not recognize Logitech webcam nor Canon Lide 110 scanner. Other USB device (such as thumb drives, keyboard and mouse) work without problem. Also, for webcam, I have relaxed security so webcam is not blocked. FYI, when 5,1 arrived it had High Sierra and it did recognize scanner, but not webcam.
I'd appreciate any feed back on what I might do to resolve USB problem.
