Hi Feklar, I'm having the same exact trouble as you. I too have a 890FX board, Asus Crosshair IV with the same NEC usb controller. I just did a clean install of Windows 7 pro because I tried Windows 10 and had problems with my ATI drivers as a matter of fact I had problems with my usb port drivers, that's why I did a clean install, they all work now. I'm interested in what the solution is.
