USB PCIe card conflicts do occur. In my case I didn’t do my full research. I am still having issues with my USB devices disconnecting on the AMD system. The latest update did fix my one USB Type C connection so at least we are good on that front. The Eluteng USB 3.1 PCIe Expansion Card 10Gbps is a good overall product and did the trick.
