Recently one of my front USB 3 ports started giving me the USB device not recognized error. No matter what device I plug in, ie a mouse, keyboard etc, Strangely enough, it does allow me to sill charge my mobile so I know it is producing power.
My case has 2 USB 3 ports in the front that are connected to the MOBO with a Y splitter. So I would reason since 1 of the USB ports does work and the other does not, the issue is with the actually port and not the mother board.
I did try un plug my system for a while to see if that would work per youtube suggestions and nothing. I was going to up date my drivers but I then remembered what I mentioned one of the ports does work.
