2 * Driver for USB Windows Media Center Ed. eHome Infrared Transceivers

Jarod Wilsonfda516b2011-07-18 16:54:29 -03004 * Copyright (c) 2010-2011, Jarod Wilson <jarod@redhat.com>
Jarod Wilson66e89522010-06-01 17:32:08 -03005 *
6 * Based on the original lirc_mceusb and lirc_mceusb2 drivers, by Dan
7 * Conti, Martin Blatter and Daniel Melander, the latter of which was
8 * in turn also based on the lirc_atiusb driver by Paul Miller. The
9 * two mce drivers were merged into one by Jarod Wilson, with transmit
10 * support for the 1st-gen device added primarily by Patrick Calhoun,
11 * with a bit of tweaks by Jarod. Debugging improvements and proper
12 * support for what appears to be 3rd-gen hardware added by Jarod.
13 * Initial port from lirc driver to ir-core drivery by Jarod, based
14 * partially on a port to an earlier proposed IR infrastructure by
15 * Jon Smirl, which included enhancements and simplifications to the
16 * incoming IR buffer parsing routines.
17 *
Jarod Wilsonfda516b2011-07-18 16:54:29 -030018 * Updated in July of 2011 with the aid of Microsoft's official
19 * remote/transceiver requirements and specification document, found at
20 * download.microsoft.com, title
21 * Windows-Media-Center-RC-IR-Collection-Green-Button-Specification-03-08-2011-V2.pdf
