a) Look up the device file(s) under /proc/bus/usb, they should have
   a write permission for everyone (nou relevant if you scan with
   su privileges)

b) Has the firmware file got the correct permissions?

c) Did you install SANE to /usr/local ? Sometimes it helps to
   link the sane.d directory to /etc:
   ln -s /usr/local/etc/sane.d /etc/sane.d
