proc/bus/usb does not exist?

        Although I can't be sure as I don't use USB, I doubt you'll get 
a /proc/bus/usb at boot time unless both CONFIG_USB and 
CONFIG_USB_DEVICEFS are set to yes. Try loading the modules by hand, 
then see if /proc/bus/usb exists. If loading them by hand gets you a 
/proc/bus/usb, then just compile them into the kernel and you'll have it 
at boot time.
