[sane-devel] Epson Perfection 4490 Photo

[Ralph Little]

Hi,
The 4490 is not currently supported by sane. I don't believe that the 
epson2 backend would necessarily help here, despite what our website says.
I think that the intention was that it *could* be supported by the 
epson2 backend but does not currently. It is a little confusing.

If I understand correctly, we rely on a binary-only backend from Epson.

Cheers,
Ralph
