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. -- Walter Dnes <waltd...@waltdnes.org> I don't run "desktop environments"; I run useful applications
