Hi, don't know if I'm right here but found on my Gentoo (~amd64) system that the file /etc/udev/rules.d/70-libsane.rules doesn't has the configuration for my scanner (Brother DCP-185C), here is the relevant section:
# Brother DCP-185C ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="0205", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes" I just found at the beginning of the above mentioned file, that non listed scannes should be mailed to this email-adress. I would be happy to hear a reply best regards Matthias
