[sane-devel] HP PSC 1310 scanner

[m. allan noah]

I think that machine is supported by the hplip project's hpaio
backend? I notice that the fedora changelog for that package says:

* Wed Sep 18 2013 Tim Waugh <twaugh at redhat.com> - 3.13.9-2
  - Applied patch to avoid unix-process authorization subject when using
    polkit as it is racy (bug #1009541, CVE-2013-4325).

So I wonder if the bug is in hpaio?
