 due to the way sanei_config_attach works, reading the config
 file will trigger a scan of all the devices, which I would rather
 avoid when the user specifies a device in sane_open().

 the whole config system probably needs an overhaul, as
 there's much duplicate code in a lot of drivers.

 we need something to parse the configuration on startup
 and act on it at a later stage, but I don't have the time do
 write it.

 so if this patch works, it's the best I can do right now ;)
