To get my DCP 7030 scanner working in Ubuntu 12.04 i386, I had to do the following:
1) Install http://www.brother.com/pub/bsc/linux/dlf/brscan3-0.2.11-4.i386.deb from http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_scn.html#brscan3 2) Add the following two lines in /lib/udev/rules.d/40-libsane.rules, under line 40 (LABEL="libsane_usb_rules_begin"): # Brother scanners ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes" 3) Plug in scanner - no system reboot or udev restart necessary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/478761 Title: failed to start scanner: Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xsane/+bug/478761/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
