? Ususally you don't need to set a path for libraries. Sometimes it's
necessary to set LD_LIBRARY_PATH or edit /etc/ld.so.conf for libaries
in /usr/local/lib, but not in /usr/lib.

If you really set the variable or file to "/usr/lib/sane/" that's
wrong. It won't work. Just set it to "/usr/lib", but this shouldn't be
necessary as this is the default.

The linker shouldn't search /usr/lib/sane/ at all.

That's the wrong library. Looks like this is a link to libsane-v4l.so.
It should find /usr/lib/libsane.so.1, which is libsane-dll.so in
reality.

The v4l (Video for Linux) backend opens its config file...

> open("/dev/video0", O_RDWR)             = -1 EBUSY (Device or  resource busy)
[...]

and tries to open some video devices...

> open("artec:/dev/scanner", O_RDWR)      = -1 ENOENT (No such file or directory)

Now it tries to open the file that was given on the command line. It
will fail, because of the artec:.

That's because your frontend only loads the v4l backend. No other
backends are loaded. I don't know whi there is a lbsane.so in
/usr/lib/sane/ in the first place. But your real problem is, that you
put /usr/lib/sane in ld.so.conf or LD_LIBRARY_PATH.

Please remove it and try again to get the log file I wrote about in my
previous mail.
