The uhci and ohci are for different USB controllers on your PC. The uhci is for VIA chipsets (and a few others - I not sure which though) and the ohci covers the rest. Only one will work with your PC. If you use lspci -vv to see the details of your USB controller it should show either UHCI or OHCI. There's also ehci for USB 2.0 devices (still need ohci/uhci for slower devices though). -- .''`.
