- * Driver for USB Windows Media Center Ed. eHome Infrared Transceivers
- *
- * Copyright (c) 2010 by 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.

- * - SET_CARRIER_FREQ sets a new carrier mode and frequency
