So I take it the above means that sane-find-scanner returns no
information on your scanner, and scanimage -L will also fail? (BTW:
you may need some sort of frontend AKA GUI; something like the Sane
Project's frontend, or XSane's frontend).

I just checked /usr/local/etc/sane.d/ and there seems to be no backend
for this scanner, IFF the backend for this model of 3400 is
sane-niash[1]. In dll.conf, there is a line for niash; I suggest
trying to put this after the "niash" in the dll.conf file:

 :/dev/uscanner0

so that you have this line:

niash::/dev/uscanner0

then reboot, to see if it works. You can read about it in the man page
for dll.conf, sane-dll.

I think this might work, as there is an entry in /usr/local/lib/sane/:

~ $: grep -i niash /usr/local/lib/sane/*
Binary file /usr/local/lib/sane/libsane-niash.so matches
Binary file /usr/local/lib/sane/libsane-niash.so.1 matches

But I dont' know, since my HP is a 2200C.

And you know that your USB port works, because you use XP on this
machine, correct?

You will also need to set up device bits, in /etc/devfs.conf:

#####Scanner
perm    uscanner0       <the perms you wish to have, like 0660 or 0666>

That should be all you need.

I suggest here: <http://xsane.org/> 
and here: <http://www.sane-project.org/>.


[1] The Sane Project indicates that it is new; so perhaps that backend
    has not yet made it into the distribution? I don't know...
