This gets tiring.  I wish developers wouldn't count on
having the latest, greatest version of every library
they depend on.  OpenBSD 3.6 and 3.7 come with
libusb-0.1.7p2 in the ports collection.  I tried
downloading libusb-0.1.10a.tar.gz and building it, but
I got errors compiling.  OpenBSD-current has
libusb-0.1.10a in the ports so maybe in another few
months at the next release it'll be the standard
version.  I tried grabbing it anyway and building
under OpenBSD 3.6 (not recommended) and it also gave
(different) errors compiling.  With my luck by the
time OpenBSD supplies libusb-0.1.10a Sane will
probably want a newer version.

I just built sane-backends-1.0.14.tar.gz and installed
it, and I don't get the "libusb not available" when I
run sane-find-scanner -v.  I'll have to wait until I
get the laptop home to connect to my scanner and see
what happens.

Meanwhile I picked up an HP 3300C on eBay for $10
which I expect Monday.  The status of that is listed
as complete, and I expect to keep it here at work.
