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

fda516b7 | 4 | * Copyright (c) 2010-2011, Jarod Wilson <jarod@redhat.com> |
66e89522 JW |
5 | * |
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 | * | |

19 | * remote/transceiver requirements and specification document, found at | |
