USB ports can make use of (AFAIK) three different modules: "ohci_hcd" - loaded for VIA and Intel host controllers-, "uhci_hcd" -loaded for NEC based ones- (USB 1.1) and "ehci_hcd" (USB 2.0). The only way I'm aware to enforce the use or one of them is by loading/ unloading the "offending" modules, for example: # Unload ehci modprobe -r ehci_hcd Greetings, -- Camaleón -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
