Scanner Needs Root Access?

[Scarletdown <scarletdown@gmail.com>]

I was recently given a brand new Epson Stylus NX300 Printer/Scanner/Fax,
and have been trying to get it all working properly.  Printer functions
are working fine.  For the scanning functions, I installed the iscan
package.  The device is scanning fine.  However, it will only work for
root.  This seems rather retarded, a real head scratcher.

How can I get this working as a normal user, since there is no logical
reason why one would need root privileges to use a scanner?

So far, I have added myself to the scanner and saned groups, and made
this entry in /etc/udev/rules.d/z60_libsane.rules

# EPSON Stylus NX300 | EPSON Stylus NX300 | EPSON Stylus NX300
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="0848", MODE="660",
OWNER="lp", GROUP="scanner", ENV{libsane_matched}="yes"

And even went so far as to chmod 0666 /proc/bus/usb/004/007 as per the
instructions in the manual for iscan.

But after all that, I still can't run iscan or otherwise access the
scanner (like through the GIMP plugin) without being root or using sudo.
