I've tried chmod on the /dev files, but that doesn't stick. I'm not surprised: I assume that the device files are set up on the fly, but I don't know how to control the permissions. I found your answer...
... check section 5.3 of this FAQ:
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: [ljm@ronsard ~]$ scanimage -L device `umax:/dev/sgd' is a UMAX Astra 1220S flatbed scanner [ljm@ronsard ~]$ 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. :-( -- Bob Kline http://www.rksystems.com mailto:bkline@rksystems.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
