Hi. I've got the same scanner, and had the same problem.

Hopefully you'll have found the /etc/sane.d directory, the
artec_eplus48u.conf configuration file, and put the "Artec48.usb" file
in /usr/share/sane/artec_eplus48u/, like it asks.

I must admit that I thought I'd done that, and was still getting the
error message.

Some research lead me to man sane-artec_eplus48u and the
SANE_DEBUG_ARTEC_EPLUS48U environment variable.

Running
    export SANE_DEBUG_ARTEC_EPLUS48U=9
    xsane
gave a whole bunch of output, including
    [artec_eplus48u] Try to open firmware file: "/usr/share/sane/artec_eplus48u/Artec48.usb"
    [artec_eplus48u] Cannot open firmware file "/usr/share/sane/artec_eplus48u/1200.usb"
    [artec_eplus48u] download_firmware_file failed

A bit of headscratching lead me to realise that I'd mis-spelled the
directory. Whoops!

In any case, I hope this helps. I hope the export variable helps you
track down what's going wrong for you.

James.
