The USB code specifically needs the /proc/bus/usb/devices file,
which isn't available on non-linux platforms such as FreeBSD.

For FreeBSD there is a patch, which didn't work for me:
http://www.freebsd.org/cgi/cvsweb.cgi/ports/palm/gnomepilot2/files/patch-gpilotd__gpilotd.c?rev=1.2&content-type=text/x-cvsweb-markup

So.. it's a bit of a mess on non linux systems.
