You're facing challenges with your ASRock Z370 Extreme 4 motherboard. The USB 3.0 device isn't being recognized by any USB ports, and the installed driver seems incorrect—Microsoft lists Intel ® instead of the correct 3.1 version. Despite removing and reinstalling the driver, the issue persists. Your support team has ruled it a faulty board, but you're hesitant to replace it if a fix isn't possible. You're using Windows 10 64-bit with the latest BIOS, and drivers are up to date. Consider checking for firmware updates from ASRock or contacting their support for further troubleshooting steps.
I checked the installation guide at the provided link and confirmed the steps. I also looked at the BIOS version page, noting there are two versions of BIOS 4.20 available. I considered installing the larger 13.04MB version, though I’m not sure if it’s necessary.
It’s a very long wire. Occasionally things occur. Also, for various reasons, firmware updates can get quite messy. Rarely does it happen, but it has. That’s why one redownload and reinstall just to be safe is necessary.
