I am using Logitech. I have also a Elgato 4K Webcam. All other devices except for the two capture cards are running normal. But I tried several capture cards and tried them on other PCs as well. It’s just on this PC. Reinstalling everything didn’t he...

I am having USB problems as well. I cannot use any external capture card - the Elgato S60 and KRATOS THEIA4K is not working for me. I tried literaly everything ... this is the second board - same issue. I don't get this.
