+ *
+ * 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 an 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.
