From 32f0f605efa293430a47d60bb857695ff6937d21 Mon Sep 17 00:00:00 2001
From: Dean Camera <dean@fourwalledcubicle.com>
Date: Thu, 14 May 2009 10:07:08 +0000
Subject: Removed all user pipe/endpoint interrupt APIs, added internal library
 support for interrupt driven control endpoints when in device mode by
 defining INTERRUPT_CONTROL_ENDPOINT token and passing it to the compiler via
 the -D switch.
