perhaps pre-install is not called because the module was not unloaded.

i thought hotplug can call the script in a usermap in prior to loading
the usb module ?  (at least, the hotplug stuff on suse distro does it,
initializing the ALSA stuff before loading snd-usb-audio to keep the
consistency.)  if so, the script should be triggered from hotplug.
