34 * \details
35 * This class provides a Funcube Dongle control block by wrapping
36 * th USB HID control interface of
37 * the Funcube Dongle into one convenient source block.
38 *
39 * The Funcube Dongle needs to have firmware 18f or later for the
40 * control interface to work properly. As of early 2011, FCDs
41 * still come with firmware 18b. You can use qthid 2.2 (not 3) to
42 * upgrade the firmware: http://qthid.sf.net
