OK, it doesn't work by scanning /proc/whatever for USB scanners and
mapping them to device files. This is because the scanner module will
find a scanner, assign a major/minor number to it, but without devfs,
it will have no idea what device files have these major/minor
number. You can scan all know device files for the major/minor
numbers, but that isn't really elegant.

Just to make things clear, I am not talking about checking whether or
not a device is USB, I'm concerned about scanimage -L in the first
place, that is finding all USB scanners connected to the computer.
