Public bug reported: I'm not really sure which package this problem is in. This report is from "ubuntu-bug sane".
I tried "ubuntu-bug libsane" but it went to sane-backends. linda@gazelle:~$ scanimage -L device `brother4:bus2;dev1' is a Brother DCP-8155DN USB scanner linda@gazelle:~$ scanimage -T scanimage: rounded value of br-x from 215.9 to 215.88 scanimage: rounded value of br-y from 355.6 to 355.567 scanimage: sane_start: Invalid argument I originally reported the bug here (comments of elindarie): https://bugs.launchpad.net/bugs/1312594 and here https://bugs.launchpad.net/bugs/1380414 where I also uploaded some gscan2pdf log and config files. Gscan2pdf also gives "invalid argument". I installed the Brother drivers. The scanner is working with an older Debian laptop (32-bit) but not a newer Ubuntu 14.04 (64-bit) laptop. Added the following line to /lib/udev/rules.d/40-libsane.rules: ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="0293", ENV{libsane_matched}="yes" If someone could tell me what more debugging to do - where to put print statements into a driver and recompile it into a development location for testing, I would gladly compare its output to that from the working Debian laptop. Thank you.
