I believe the scanner group is no longer part of a Ubuntu installation.
I'm running precise and couldn't locate it there.

The discussion so far deals with the permissions of the device. But I think
what is more important is that by default, the user is not part of the group

Ubuntu 10.04.

If anybody is still looking at this, you might like to know I got it
working on Jaunty. The fix was too simple, it only took running the
command:
sudo chown rich /dev/sg6
where rich is my login userid
Both scanners now work without requiring root. They work with Sane and
Vuescan.

Just when you thought it was safe..
This thing has taken a strange twist. After a reboot, the Epson scanner
no longer works. If I rerun the command:
sudo chown rich /dev/sg6
Things work again. What makes it even more weird is that /dev/sg6 ti the
port for the Nikon scanner which
I also am having permissions issues with an Epson Perfection 2450 Photo scanner.
I have two scanners attached, both are IEEE1394 interfaces. The Nikon Coolscan
works fine and is seen by xsane and vuescan.
The problem is with an Epson Perfection 2450 Photo which is not seen by either
app.
I should add that I am running Jaunty 9.04 64bit

In Intrepid I had to create a new /etc/udev/rules.d/45-libsane.rules
file with the following lines:
# Hewlett-Packard ScanJet 3570c
SYSFS{idVendor}==03f0, SYSFS{idProduct}==2005, MODE=664, GROUP=scanner
Now udev set correct permissions and ownership at boot for my scanner.

unplugging usb scanner and pluggin it in again does not solve the
problem.
maybe console-kit does not pick up the active console user.
restart of hal does not cure problem.

Akkena:
'apt-get -f install' installs packages to fill the missing depencies. (like the

i guess this problem was caused because the system was upgraded from a
previous system, instead of clean installed.

Found it. When udev is started with the scanner plugged in, the device
entry is created like:
crw-rw-r-- 1 root root 189, 389 May 8 11:03 /dev/bus/usb/004/006
after unplugging/replugging it is:
crw-rw-r--+ 1 root root 189, 390 May 8 11:05 /dev/bus/usb/004/007
notice the '+'.

I'm lost. After inspection of the udev sources it looks like udev does
not save state between restarts except for the /dev/.udev/rules.d
directory.
So, it might be that the problem was cured by some update since last
reboot 10 hours ago, or that the problem was fixed by unplugging and
plugging

Solved. Looks like there were some old config files in /etc/hal:
/etc/hal/hald.conf
/etc/hal/fdi/preferences.fdi.bak
as at least /etc/hal/hald.conf was mentioned in 'dpkg -L hal' i did:
dpkg --purge --force-depends hal
rm /etc/hal/hald.conf /etc/hal/fdi/preferences.fdi.bak
apt-get -f install

Same problem here on Hardy Beta, amd64 with a Canon LiDE 20 (usb). My
user has not been in the scanner group, either. Adding the user to this
group does not solve the problem, using xsane as root works.

yes, that is probably what sets the permissions, and also the thing

I'm trying hardy heron beta1 and I have this same problem.
(NB, commands below ran after changing permissions, so xsane is not running as
root)
when I run lsusb, I can see the device is 004:004:

Bus 004 Device 004: ID 04b8:011b
Simon - you solution worked for me to.. interesting to note the
permissions of the relevant USB device:
$ ls -lah

Should this bug be assigned to udev as well?
