Hi sane-devels,

I'm hoping someone here can help solve my issue of not being able to use my Epson 4180 scanner with SANE. Below are the details of my steup and what I have tried so far.

Scanner:
Epson Perfection 4180 Photo

Operating System:
Linux Mint 17.3
$ uname -a
Linux 3.19.0-32-generic #37~14.04.1-Ubuntu SMP Thu Oct 22 09:41:40 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Version of SANE:
$ scanimage -V
scanimage (sane-backends) 1.0.23; backend version 1.0.23

$ dpkg-query -l *sane* | grep ^ii
ii libsane:amd64 1.0.23-3ubuntu3.1 amd64 API library for scanners ii libsane-common 1.0.23-3ubuntu3.1 amd64 API library for scanners -- documentation and support files ii sane 1.0.14-9 amd64 scanner graphical frontends ii sane-utils 1.0.23-3ubuntu3.1 amd64 API library for scanners -- utilities ii xsane 0.998-5ubuntu1 amd64 featureful graphical frontend for SANE (Scanner Access Now Easy) ii xsane-common 0.998-5ubuntu1 all featureful graphical frontend for SANE (Scanner Access Now Easy)

$ dpkg-query -l *scan* | grep ^ii
ii iscan 2.10.0-2 amd64 simple, easy to use scanner utility for EPSON scanners ii iscan-plugin-gt-f600 1.0.0-2 amd64 Image Scan! plugin for the GT-F600 / Perfection 4180 ii simple-scan 3.12.1-0ubuntu1 amd64 Simple Scanning Utility

From the Epson support download site I can download: iscan-2.10.0-1.c2.i386.rpm
I turn that into a package that I can install on my system and install it:
$ sudo alien --target=amd64 --scripts iscan-2.10.0-1.c2.i386.rpm
$ sudo dpkg --install iscan_2.10.0-2_amd64.deb

I found that the "/usr/share/doc/iscan-data/SUPPORTED-DEVICES" file has the following line in it:
    - Epson Perfection 4180 PHOTO (requires iscan-plugin-gt-f600)

From the Epson support download site I can download: iscan-plugin-gt-f600-1.0.0-1.c2.i386.rpm

$ scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

$ scanimage -d
scanimage: no SANE devices found

My "/etc/sane.d/dll.conf" has everything commented out except the following line:
    epkowa

My "/etc/sane.d/epkowa.conf" only contains:
    scsi EPSON
    usb
    usb 0x04b8 0x0118

$ ls /usr/lib/sane
libsane-epkowa.la  libsane-epkowa.so.1 libsane-epkowa.so.1.0.15


Not sure it is related to the scanner not being identifed, but when I run iscan I get an error:
$ iscan

$ dpkg-query -l *libjpeg* | grep ^ii

I have searched the web for days trying to get my scanner working. No luck so far. Does anyone have an idea about how to solve my issue?

Thank you in advance.
