[sane-devel] Scanner Access on FreeBSD

[Tom Garvin]

I'm looking for help in opening access to a scanner on FreeBSD.  My
setup is:

 

OS:                  FreeBSD v6.2

SANE:              current versions of frontend and backend from ports

Scanner:           Avision AV220C2

 

Situation is that everything works from root... scanadf scans a document
just fine.  Debug output as root is almost identical to what you see
below, except that it finds one scanner and lists it properly.  My
problem is that I can't get the saned user to work.  I've followed the
steps at
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/scanners.html
to no avail.  I realize that it must be a permissions issue, but can't
see the solution.  I think the debug output shows that saned user can
read the /usr/local/etc/sane.d files.  And I think device permissions
are set to allow saned access through the operator group.  So I'm a
little stumped and appreciative of any help.
