It doesn't need proprietary modules.  As the V700 has only been added
in CVS after 1.0.18 released, I would assume it is not in the list of
scanners used by udev/hotplug.  Add a line similar to the ones already
in /etc/udev/rules.d/*libsane.rules or
/etc/hotplug/usb/libsane.usermap to match the Perfection V700.  Just
replace the USB product ID to match your device (0x012c).

Hope this helps,
