[sane-devel] Nikon Coolscan IV recognized but fails scanimage with "Invalid argument"

[Michael Hess]

*Hello Allan:*

I went by this:

from: http://www.sane-project.org/source.html

    *Linux*
    Most Linux distributions package SANE with modifications required to
    support their authentication or permissions systems. We recommend
    you use the vendor's packages. If you need a more updated version of
    SANE, be prepared to build from source, and ask on a distro-specific
    forum for advice.

synaptic lists the installed and latest versions as the same

     sane: installed 1.0.14-9 | latest 1.0.14-9
     libsane: 1.0.20-13ubuntu2 | 1.0.20-13ubuntu2
     sane utils: 1.0.20-13ubuntu2 | 1.0.20-13ubuntu2

 From the backends list (https://alioth.debian.org/frs/?group_id=30186),
it appears that the "latest version" is from 2004.
Well ... argh ... that's how I learn.

I did go ahead and download sources for sane 1.0.22. I compiled and 
installed it (3 times),
had to get supporting files (libusb-dev and libsane), and replug the 
scanner and restart
the machine several times.

But ... it is now working well enough.
Phew.

Thank You,
*Mike*
