Hi Chrysn,

We should avoid multiple declarations in the code.

I'll simply replace "Canon i-SENSYS MF4550d" with "Canon i-SENSYS MF4500
Series" in the code and commit the changes, soon.

It's correct, there are MF4500 Series scanners with and without
wireless. But we cannot differ wireless from wired only devices because
we identify scanners by their USB PID and they have the same.

Many thanks for your help.
