unpacking using ALIEN and a .RPM may be the issue? This might be solved using a .DEB file from linux.avasys.jp/drivers/iscan/2.28.1 which is the most recent.

I know this might be very late, but I just encountered the same issue, with my EPSON scanner. The problem is multifaceted.
The sane package has changed a lot. The lib location is changed.
You need to use dpkg -L to check if your package installed the libs into wrong places. For example /usr/lib/sane. If this is true, cd to that location then:
# ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-gnu/sane
Since the po's scanner still working under root, he should not had this problem.
the new ubuntu updated the scanner policy.
Now a user need to be in saned and scanner group to use scanner. However, just add yourself to those group is not enough. Your scanner has to be properly owned by the scanner group. Otherwise, even you change the device permission to mode 777, it still need root to use scanner. Here is how you can automatically change the scanner's group during hotplugin.
Create a rule for the device
/etc/udev/rules.d $ cat 80-scanner.rules
# change device EPSON owner group
ATTRSmanufacturer=="EPSON", DRIVERS=="usb", SUBSYSTEMS=="usb", ATTRSidVendor=="04b8", ATTRSidProduct=="0142", GROUP="scanner"
Test the rule
use udevadm control –reload to load your rule.
use lsusb to find your device /dev path
to check if your rule is functioning, test with the follow command:
# udevadm test $(udevadm info -q path -n /dev/bus/usb/<bus>/<device>) 2>&1 | grep -i group --color
If your rule is correct you should see the group changed to scanner from root.
Finally, disconnect your scanner and reconnect it. Then try follow commands without sudo
$ sane-find-scanner
$ scanimage -L
Your scanner should functioning correctly
