Wombat's Laws of Computer Selection: (1) If it doesn't run Unix, forget it. (2) Any computer design over 10 years old is obsolete. (3) Anything made by IBM is junk. (See number 2) (4) The minimum acceptable CPU power for a single user is a VAX/780 with a floating point accelerator. (5) Any computer with a mouse is worthless.

I haven't checked lately, but it's likely that modern udev sets permissions up correctly. This script should work if it doesn't. Original readme: Just a short word about setting up sane. You've just plugged in your shiny new scanner, selected the right backend and tried to run xsane but get permision denied. So you run it as root and find it works. Great but running as root in the long term is not the answer. What you now need to do is set up correct permissions to run xsane as a normal user. Hopefully you are in the 'scanner' group. If not, get yourself in it: Replace your needed groups as you like, but as root it's roughly: usermod -G floppy,audio,video,cdrom,plugdev,power,scanner username groups username Now find the usb device that your scanner is using: scanimage -L Hopefully you get output like the following: device `snapscan:libusb:001:002' is a EPSON EPSON Scanner1 flatbed scanner The parts we are interesting in are the numbers 001 and 002. This means that the scanner is using /proc/bus/usb/001/002 and this is the file we need to change permissions of: as root again: chown root:scanner /proc/bus/usb/001/002 chmod g+rw /proc/bus/usb/001/002 This sets group ownership and allows users in scanner group rw access. Now you should be able to scan. But you've just resumed your pc from hibernation or suspension and now the usb device has changed. That's why I created the scanperms script - it will find your scanner and set the permissions. You can source/run the file from your hibernation script and /etc/rc.d/rc.local
