- * lirc_igorplugusb - USB remote support for LIRC
- *
- * Supports the standard homebrew IgorPlugUSB receiver with Igor's firmware.
- * See http://www.cesko.host.sk/IgorPlugUSB/IgorPlug-USB%20(AVR)_eng.htm
- *
- * The device can only record bursts of up to 36 pulses/spaces.
- * Works fine with RC5. Longer commands lead to device buffer overrun.
- * (Maybe a better firmware or a microcontroller with more ram can help?)
- *
- * Version 0.1  [beta status]
- *
- * Copyright (C) 2004 Jan M. Hochstein
- *	<hochstein@algo.informatik.tu-darmstadt.de>
- *
- * This driver was derived from:
- *   Paul Miller <pmiller9@users.sourceforge.net>
- *      "lirc_atiusb" module
- *   Vladimir Dergachev <volodya@minspring.com>'s 2002
