Sorry, I have misunderstood the man page.
Perhaps I am the only one who misunderstood the man page but if not
you may add this "Once the scanner is recognized, the backend will
talk to the scanner and find out it's capabilities automatically."
to the man page to make it more clear for all users.

I guess this (i.e. find out it's capabilities automatically)
is not possible for all scanners (i.e. for all backends).

Therefore for other backends an explicite hint which compatible
model it must use may be necessary.
Perhaps it may be even useful for the epson backend if the automatism
results only some generic scannig capabilities (i.e. level B3) but with
an explicite hint it may be possible to use more scanner features.
