Scanner of my Canon MP510

Hello all !
I have a little problem with my Canon MP510's scanner. I can scaning by typing a command in my terminal but I can't use Xsane correctly.
I can get the outline but when I try to scan normally I get an I/O Error...
Somebody would know how to help me ?
Thanks a lot

I read on the wiki that we need scanner group rw permissions. But how I can make that ?
Thanks for your help.
PS : the normal user is in the scanner group

Re: Scanner of my Canon MP510

I found this on the ubuntuforums :

Open /etc/udev/rules.d/40-permission.rules as root and change usb device subsystem to mode=0666.

But I haven't a file named "40-permission.rules" in my rules.d directory. So where can I find the usb permission in arch ?
Thankyou.

Re: Scanner of my Canon MP510

Every distro customizes udev differently. Try e.g.:

grep scanner /etc/udev/rules.d/*

Re: Scanner of my Canon MP510

Thanks for your help.
I changed the permissions for all usb buses.

/etc/udev/rules.d/50-udev-default.rules~:SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0666"

and now I have :

ls -la /dev/bus/usb/*
/dev/bus/usb/001:
total 0
drwxr-xr-x 2 root root      0 jui  2 13:01 .
drwxr-xr-x 5 root root      0 jui  2 13:01 ..
crw-rw-rw- 1 root root 189, 0 jui  2 13:01 001
crw-rw-rw- 1 root root 189, 1 jui  2 13:01 002

/dev/bus/usb/002:
total 0
drwxr-xr-x 2 root root           0 jui  2 13:13 .
drwxr-xr-x 5 root root           0 jui  2 13:01 ..
crw-rw-rw- 1 root root    189, 128 jui  2 13:01 001
crw-rw-rw- 1 root scanner 189, 130 jui  2 13:13 003

/dev/bus/usb/003:

drwxr-xr-x 2 root root        0 jui  2 13:01 .

crw-rw-rw- 1 root root 189, 256 jui  2 13:01 001
