It did exist on my 5.4 machine....but then:

Roland, do you know if niash.conf is in, and/or unique to, the 6.x
release? I do not see it on my 5.4 machine. Since sane is a port, I
don't think it would be in one release, but not another. It is a new
sane backend, so perhaps it is not yet in the ports tree, somehow?

Here is pkg-plist from sane-backends on 5.4:

About HP3300c SANE backend

This project is about writing a Linux SANE backend for the HP3300c USB
color scanner. Support for other scanners with very similar chipsets,
like the HP3400c, HP4300c and the Agfa Touch is also planned.

Operating System: All BSD Platforms (FreeBSD/NetBSD/OpenBSD/Apple Mac
OS X), All POSIX (Linux/BSD/UNIX-like OSes), FreeBSD, Linux, NetBSD,
OpenBSD License: GNU General Public License (GPL)

Is it perhaps sufficient to create the niash.conf file? I wonder,
because some of the conf files look like they may have aspects that
are necessary for the correct functioning of the scanner.

Raccoon...I think it can be solved; but it may depend on whether or
not there is a backend; or, perhaps, if the dll.conf file entry is
sufficient. I do not know which, if either, is the case.

.sig is .tired.
