| 2 | * Driver for USB Windows Media Center Ed. eHome Infrared Transceivers |
| 3 | * |
| 4 | * Copyright (c) 2010 by Jarod Wilson <jarod@redhat.com> |
| 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. |

| 323 | * - GET_CARRIER_FREQ gets the carrier mode and frequency of the |

| 325 | * meaning clk of 10000000, 2500000, 625000 or 156250, and FF is |
| 326 | * ((clk / frequency) - 1) |
| 327 | * - GET_RX_TIMEOUT fetches the receiver timeout in units of 50us, |
| 328 | * response in the form of 9f 0c msb lsb |
| 329 | * - GET_TX_BITMASK fetches the transmitter bitmask, replies in |
| 330 | * the form of 9f 08 bm, where bm is the bitmask |
| 331 | * - GET_RX_SENSOR fetches the RX sensor setting -- long-range |
| 332 | * general use one or short-range learning one, in the form of |
| 333 | * 9f 14 ss, where ss is either 01 for long-range or 02 for short |
| 334 | * - SET_CARRIER_FREQ sets a new carrier mode and frequency |
| 335 | * - SET_TX_BITMASK sets the transmitter bitmask |
| 336 | * - SET_RX_TIMEOUT sets the receiver timeout |
| 337 | * - SET_RX_SENSOR sets which receiver sensor to use |
