+ *
+ * Copyright (c) 2011, 2012 Anssi Hannula <anssi.hannula@iki.fi>
+ * Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
+ *
+ * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
+ * porting to the 2.6 kernel interfaces, along with other modification
+ * to better match the style of the existing usb/input drivers. However, the
+ * protocol and hardware handling is essentially unchanged from 2.1.1.
+ *
+ * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
+ * Vojtech Pavlik.
+ *
+ * Changes:
+ *
+ * Feb 2004: Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.2.0
+ * Jun 2004: Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.2.1
+ * Added key repeat support contributed by:
+ * Vincent Vanackere <vanackere@lif.univ-mrs.fr>
+ * Added support for the "Lola" remote contributed by:
+ * Seth Cohn <sethcohn@yahoo.com>

+ *
+ * Hardware & software notes
+ *
+ * These remote controls are distributed by ATI as part of their
+ * "All-In-Wonder" video card packages. The receiver self-identifies as a
+ * "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
+ *
+ * The "Lola" remote is available from X10. See:
+ * http://www.x10.com/products/lola_sg1.htm
+ * The Lola is similar to the ATI remote but has no mouse support, and slightly
+ * different keys.
+ *
+ * It is possible to use multiple receivers and remotes on multiple computers
+ * simultaneously by configuring them to use specific channels.
+ *
+ * The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
+ * Actually, it may even support more, at least in some revisions of the
+ * hardware.
+ *
+ * Each remote can be configured to transmit on one channel as follows:
+ * - Press and hold the "hand icon" button.
+ * - When the red LED starts to blink, let go of the "hand icon" button.
+ * - When it stops blinking, input the channel code as two digits, from 01
+ * to 16, and press the hand icon again.
+ *
+ * The timing can be a little tricky. Try loading the module with debug=1
+ * to have the kernel print out messages about the remote control number
+ * and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
+ *
+ * The driver has a "channel_mask" parameter. This bitmask specifies which
+ * channels will be ignored by the module. To mask out channels, just add
+ * all the 2^channel_number values together.
+ *
+ * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
+ * ignore signals coming from remote controls transmitting on channel 4, but
+ * accept all other channels.
+ *
+ * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
+ * ignored.
+ *
+ * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
+ * parameter are unused.

+ *
+ * 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

+ * USB RedRat3 IR Transceiver rc-core driver
+ *
+ * Copyright (c) 2011 by Jarod Wilson <jarod@redhat.com>
+ * based heavily on the work of Stephen Cox, with additional
+ * help from RedRat Ltd.
+ *
+ * This driver began life based on an old version of the first-generation
+ * lirc_mceusb driver from the lirc 0.7.2 distribution. It was then
+ * significantly rewritten by Stephen Cox with the aid of RedRat Ltd's
+ * Chris Dodge.
+ *
+ * The driver was then ported to rc-core and significantly rewritten again,
+ * by Jarod, using the in-kernel mceusb driver as a guide, after an initial
+ * port effort was started by Stephen.
+ *
+ * TODO LIST:
+ * - fix lirc not showing repeats properly
+ * --
+ *
+ * The RedRat3 is a USB transceiver with both send & receive,
+ * with 2 separate sensors available for receive to enable
+ * both good long range reception for general use, and good
+ * short range reception when required for learning a signal.
+ *
+ * http://www.redrat.co.uk/
+ *
+ * It uses its own little protocol to communicate, the required
+ * parts of which are embedded within this driver.
