The kernel's menuconfig help text for EHCI says: "If you configure EHCI, you should probably configure the OHCI (for NEC and some other vendors) USB Host Controller Driver or UHCI (for Via motherboards) Host Controller Driver too." For OHCI it states: "On most non-x86 systems, and on x86 hardware that's not using a USB controller from Intel or VIA, this is probably appropriate." It even suggests that 'lspci -v' will provide the interface type (EHCI, OHCI or UHCI) for your USB controllers. That output was accurate on a quick check of my system. UHCI's help text mentions some specific Intel & Via chipsets that are supported.
