I'm confused about what is the sane frontend or backend, or whether I should download/install another frontend or backend, if there is one. I'm not sure, but from the following, it seems like, on Ubuntu, that "sane" is the frontend, and "sane-utils" is the backend (???) .
dpkg -l | grep -i sane ii libcommon-sense-perl 3.72-2build1 amd64 module that implements some sane defaults for Perl programs ii libsane:amd64 1.0.23-3ubuntu3.1 amd64 API library for scanners ii libsane-common 1.0.23-3ubuntu3.1 amd64 API library for scanners -- documentation and support files ii libsane-hpaio 3.14.3-0ubuntu3.2 amd64 HP SANE backend for multi-function peripherals ii libsane-perl 0.05-2build1 amd64 Perl bindings for the SANE (Scanner Access Now Easy) Project ii sane 1.0.14-9 amd64 scanner graphical frontends ii sane-utils 1.0.23-3ubuntu3.1 amd64 API library for scanners -- utilities Also, the SANE website, http://www.sane-project.org, says the latest backend is 1.0.24, as of Sept. 30, 2013. The Ubuntu Software Center seems to have version 1.0.23 for sane-utils . If that is the same as the sane backend, maybe upgrading to 1.0.24 would fix this. Their web site says the changes from 1.0.23 to 1.0.24 have some bug fixes and improved USB support, etc. I don't know if it's possible, but maybe it would be simpler if the names of the sane-related files on ubuntu were the same as those at the www.sane-project.org. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1312594 Title: 14.04 won't detect common USB scanner Status in “sane-backends” package in Ubuntu: Confirmed Bug description: My multifunction Samsung SCX3200 printer is not detected by sane, but printing is fine.
