/*
 * Driver for USB Windows Media Center Ed. eHome Infrared Transceivers
 *
 * Copyright (c) 2010-2011, Jarod Wilson <jarod@redhat.com>
 *
 * Based on the original lirc_mceusb and lirc_mceusb2 drivers, by Dan
 * Conti, Martin Blatter and Daniel Melander, the latter of which was
 * in turn also based on the lirc_atiusb driver by Paul Miller. The
 * two mce drivers were merged into one by Jarod Wilson, with transmit
 * support for the 1st-gen device added primarily by Patrick Calhoun,
 * with a bit of tweaks by Jarod. Debugging improvements and proper
 * support for what appears to be 3rd-gen hardware added by Jarod.
 * Initial port from lirc driver to ir-core drivery by Jarod, based
 * partially on a port to an earlier proposed IR infrastructure by
 * Jon Smirl, which included enhancements and simplifications to the
 * incoming IR buffer parsing routines.
 *
 * Updated in July of 2011 with the aid of Microsoft's official
 * remote/transceiver requirements and specification document, found at
 * download.microsoft.com, title
