Whoops!That stumped me.I'm afraid Fedora 12 runs on a "module build-in" kernel,(I don't know the terminology so the strange phrase) cuz I can find nothing about ehci or uhci in the module list.AND, I don't know how to remove a "build-in" module.I tried to disable USB2.0 support in the BIOS,but the OEM motherboard stopped me. Could you please teach me how to remove the echi module? Thank Fei
