Writing a udev rule for a USB device, I need to change permissions.

[jtp51]

"...run scan as root or set the usbfs permission accordingly e.g. by using a hotplug script or udev rules. By default the driver looks for USB devices in /dev/bus/usb then in /proc/bus/usb. Please consult the administration handbook of your OS (keywords: udev hotplug scanner sane) for how to grant a user an access to the scanner. (You need read and write permission.)"

Err.. What?

I did a search in the Ubuntu Help Center and I found the section entitled "Writing udev rules".

This seems powerful, but I have no idea how to start. I need help writing a udev rule for a USB device, I need to change permissions for my supported Cannon Pixma MP460.

Thanks,
