[sane-devel] Epson V370 Photo scanner does not work

[szukw000 at arcor.de]

I use linux-4.4.3 (SLACKWARE, 64-Bit), sane-backends-1.0.25.

With my old HP-F2280 scanner I get:

xsane:
===============
//Bus 005 Device 009: ID 03f0:2404 Hewlett-Packard Deskjet F2280 series
dll.c:1155: ENTER full_name(hpaio:/usb/Deskjet_F2200_series?serial=CN8AL4Q2GV0534)

dll.c:1222: AFTER be->op dev_name(/usb/Deskjet_F2200_series?serial=CN8AL4Q2GV0534)

Now I have bought an Epson V370 Photo scanner.

And installed:
 iscan-data-1.36.0-1.noarch.rpm
 iscan-2.30.1-1.usb0.1.ltdl7.x86_64.rpm
 iscan-plugin-perfection-v370-1.0.0-2.x86_64.rpm
