The -L or --list-devices option requests a (partial) list of devices that  are  avail-
       able.   The  list  is  not  complete  since some devices may be available, but are not
       listed in any of the configuration files (which  are  typically  stored  in  directory
       /etc/sane.d).   This is particularly the case when accessing scanners through the net-
       work.  If a device is not listed in a configuration file, the only way to access it is
       by  its  full  device name.  You may need to consult your system administrator to find
       out the names of such devices.
