Might be a duplicate of bug #380625
** Description changed:
I'm trying Karmic Alpha 6 and had a little problem with the setup of my
- scanner. I know that it is related to the permissions on the device and
- have been able to configure it correctly on Jaunty using a widely
- available procedure that looks like this:
+ scanner. XSane reports no scanner detected but detects it if I launch
+ XSane as root.
+
+ To reproduce:
+ -Connect a USB scanner (mine is a Brother DCP-7040 multifunction machine)
+ -Install drivers provided by Brother
+ -Launch XSane as a normal user... Fail to detect scanner
+ -Launch XSane as root... Scanner detected and functional
+
+ I know that it is related to the permissions on the device and have been
+ able to configure it correctly on Jaunty using a widely available
+ procedure that looks like this:
-----
Change some values in a config file : sudo gedit
/etc/udev/rules.d/40-basic-permissions.rules
Edit "0664" to "0666" in "USB devices" section.
#Before the edit---------------------------------
# USB devices (usbfs replacement)
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664"
SUBSYSTEM=="usb_device", MODE="0664"
#After the edit----------------------------------
# USB devices (usbfs replacement)
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0666"
SUBSYSTEM=="usb_device", MODE="0666"
-----
The problem is that the "/etc/udev/rules.d/40-basic-permissions.rules"
file no longer exists at this location. Is there another file that
should be modified? Will create this file solve the problem? The problem
is not related to a driver configuration issue because everything works
when I launch XSane as root.
There are also some people that talk about adding the user to the
"Scanner" group but this group does'nt exist in the default system.
