Hello Nakamura-san,

I understand. I don't have any network based Epson scanner, so I am new
to this topic. Does it mean we maybe have to add this phrase "network
interface supported via DFSG non-free iscan-network-nt package" to the
scanner entries which your patch adds to epson2.desc?

Also, I noticed that your first version has a bugfix for these scanners:

	e2_model(s, "ET-16500 Series") || e2_model(s, "L1455 Series") || e2_model(s, "EW-M5071FT Series")

However, I couldn't find that these scanners were supported in SANE
upstream or by your patch. I guess this is why these lines were dropped
in the second version?

I already prepared to merge your patch for epson2. I'd just need to know
if we should add the phrase about the iscan package to the desc file.

Thanks and have a nice weekend!

Kind regards,

   Wolfram
