We have Epson Perfection 3490 and Canon Lide 120.

While /dev/bus/usb/001/0XX is owned by root:root,, but as well by the
scanner group (where my user is), it is not the case with Canon, the

Take a look at /lib/udev/rules.d/60-libsane.rules and /usr/share/doc/libsane/README.Debian.gz

The lsusb command should show you the vendor and product ids.
