Stop logging into Xwindows as root.
instead, login as yourself, open a terminal, and run this:
su -
It will ask for root password. if you give it correctly, you now have
a shell open as root. in that shell, run this:
chown chris. /dev/sg0
(this assumes that 'chris' is your login.) Note the '.' after chris.
This changes the owner and group. Now exit the root shell:
exit
and exit the 'chris' shell if you don't need it any more.
exit
However, all of this is a stop-gap for actually fixing the problem.
Your system should be capable of managing these permissions
automatically. What OS is this?

The scanner works as root, but not as a regular user. So we need to
adjust the permissions of the device.
The mechanism to do this differs somewhat between linux distros.
Generally, we will be editing udev (/etc/udev/rules.d) or hal
(/usr/share/hal/fdi/) rules. Or, perhaps some other mechanism. :(

run the following, as root:

if your scanner is not listed, run the following as root:
SANE_DEBUG_CANON=255 scanimage -L 2canon.log
This will produce a 'canon.log' file in the current directory. Please
send that file to the list, compressed if it is larger than 100 KB.

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).

If the

your

# Your SCSI scanner was detected. It may or may not be
supported by
SANE.
Try
# scanimage -L and read the backend's manpage.
# No USB scanners found. If you expected something different,
make
sure
that
# you have loaded a kernel driver for your USB host
controller and
have
setup
# the USB system correctly. See man sane-usb for details.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other

# can't be detected by this program.
# You may want to run this program as root to find all devices.
Once
