Is the cpu AMD? Intel machines require UHCI (USB 1.1) and AMD
machines require OHCI (USB 1.0) for lowspeed USB devices like keyboards
and mice. There's a root hub translator selection in .config that's
*SUPPOSED* to work with keyboards+mice, using only the EHCI kernel
driver, but I never could get it to work.
