I found your answer...
... check section 5.3 of this FAQ:
http://www.xs4all.nl/~ljm/SANE-faq.html#46
Thanks for your reply. I've looked at this FAQ. It says:
[[[ start quote ]]]
scanimage -L
This will give you the name of the device. For example:
[EMAIL PROTECTED] ~]$ scanimage -L
device `umax:/dev/sgd' is a UMAX Astra 1220S flatbed scanner
[EMAIL PROTECTED] ~]$
The /dev/sgd is the name of the device.
[[[ end quote ]]]
In my case, the output of scanimage -L is
device `plustek:libusb:007:002' is a Canon N1240U/LiDE30 USB flatbed scanner
which doesn't give me a name of a file but is using some other syntax.
The answer to the FAQ goes on to talk about finding the lines in the
file /etc/security/console.perms and commenting them out. There is no
such file in my /etc/security directory. In fact, I've looked at every
file that is in that directory, and almost none of the non-empty lines
in any of the files are uncommented to start with, and I promise that
none of the ones which aren't commented make any reference to the
scanner. Then the FAQ talks about "users of the device filesystem" and
"/etc/devfs/perms" which I assume doesn't apply to this installation of
SuSE, as /etc/devfs doesn't exist. The FAQ ends with "For USB scanner,
have a look at the USB-section."
So I did. That section starts of by talking about using chmod on files
in /proc/bus/usb. I don't have any files there, and that's not a
durable solution anyway ("the permissions will be reset when the scanner
is replugged or Linux is rebooted"). Then:
"One solution to set permissions on-the-fly are the Linux hot-plug tools
that should come with any current distribution. SANE itsself comes with
a hotplug script and related documentation in the tools/hotplug/
directory. Please refer to the README in that directory for the details.
You might also wish to browse through the documentation for the Plustek;
it has quite a nice section on how to set-up your USB access.
/usr/share/doc/sane-backends-*/plustek/Plustek-USB.txt"
I don't see any evidence that the statement about SANE including hotplug
tools is actually true:
$ rpm -qa | grep -i sane
xsane-0.991-32
sane-frontends-1.0.14-44
sane-1.0.18-34
$ rpm -ql sane | grep -i hotplug
$ rpm -ql sane-fontends | grep -i hotplug
$ rpm -ql xsane | grep -i hotplug
$ man hotplug
No manual entry for hotplug
I'm **way** out of my systems administration here. :-(
