There's no such thing. Things never change for no reason.

Install the iscan-data and iscan packages.
After that, scanimage -L will list your device as epkowa:... (possibly
in addition to epson2:... and/or epson:..., depending on your dll.conf).
Just use the epkowa:... listing to scanimage's -d option or select it in
your frontend scanner selection dialog.
