You have to change a little bit to run as normal user for some scanners
In Gloria/Jaunty
Edit
Code: Select all
gksu gedit /lib/udev/rules.d/50-udev-default.rules

Find
# libusb device nodes
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ... , MODE="0664"

and change 0664 to 0666
In Felicia/Intrepid
Edit
Code: Select all
gksu gedit /etc/udev/rules.d/40-basic-permissions.rules

Find
# USB devices (usbfs replacement)
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664"
SUBSYSTEM=="usb_device", MODE="0664"

Change both 0664 to 0666
Reboot for it to take effect

OK then there are two ways to deal with this
Firstly the way it was done in Elyssa and earlier (or possibly Daryna and earlier)
1. Open "/etc/fstab"
2. Add or modify a line for /proc/bus/usb as follows.
none /proc/bus/usb usbdevfs auto,devmode=0666 0 0
3. umount /proc/bus/usb
4. mount /proc/bus/usb
5. mknod -m 666 /dev/usbscanner c 180 48

or this solution
Open "/etc/udev/rules.d/45-libsane.rules"
Add the following 2 lines before "LABEL="libsane_rules_end"":
The lines to be added---------------------------
#Brother
SYSFS{idVendor}=="04f9",MODE="666",GROUP="scanner"

This has to done as root - gksu gedit
Reboot for it to take effect
The first solution is similar to this a+rw chmod /dev/bus/usb/004/002
To get that done automatically
Code: Select all
gksu gedit /etc/rc.local

add a+rw chmod /dev/bus/usb/004/002 just before the line exit 0
Again reboot
The rc.local solution shoul not be used unless all else fails - it's a "dirty workaround"

i think the libsane.rules solution did it but the filename was a little different, something like libsane-extras.rules

I did every single thing and nothing was working permanently so im not sure what made it

thanx
