Missing Usb root hub driver

[Halo_54x]

In device manager one of my usb ports shows up as unknown device and says the AMD3.1 roothub driver is missing and I've tried a couple of downloads and none of them seem to get it working again. I just need help finding the right download I'm looking for.

I went to this website and downloaded the first link
https://www.amd.com/en/support/chipsets/amd-socket-am4/b450. When I downloaded it and restarted the usb port still shows up as unknown device do I uninstall the device and download it or does it make no difference.
