+iscan needs to be started as root:

 sudo iscan

+To let users access the device which changes bus and device each time it is started, add a udev rule based on the manufacturer and device code. It's the ID 04b8:0130 but where 04b8 is EPSON and 0130 the particular model.
+<code>
+lsusb
+</code>
+Also add yourself to the saned and scanner groups (replace username with the actual username):
+<code>
+sudo adduser username saned
+sudo adduser username scanner
+</code>
+Now add the following to /etc/udev/rules.d/80-scanner.rules
+<code - 80-scanner.rules>
+# change device EPSON owner group
+ATTRS{manufacturer}=="EPSON", DRIVERS=="usb", SUBSYSTEMS=="usb", ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0130", GROUP="scanner"
+</code>
+Reload udev rules:
+<code>
+sudo udevadm control --reload
+</code>
+And test the rules replacing the bus and device number from lsusb output. This should print group id 0 in the first line, then the group id of the scanner group in the second line.
+<code>
+sudo udevadm test $(udevadm info -q path -n /dev/bus/usb/<bus>/<device>) 2>&1 | grep -i group --color
+</code>
+Disconnect the scanner and reconnect it, then try using iscan or other scanning applications.
