From 6619413096ca2cd63cdd45b422edaa6921aa39e3 Mon Sep 17 00:00:00 2001
From: Hans Petter Selasky <hselasky@FreeBSD.org>
Date: Wed, 13 Mar 2013 12:23:14 +0000
Subject: - Make the FreeBSD's USB library compile under Linux. - Fix a compile
 warning where the return value of a call to a write() function was ignored. -
 Remove redundant include files from userland USB header files. - Add some now
 needed include files to various C-files.
