 * \brief     simple small helper tool for GECKO3COM
 *
 *            with this tool you can set the serial number, hw revision
 *            and FPGA type of a GECKO3COM driven device.
 *            mainly this is the GECKO3main but the firmware could be
 *            used on other boards. \n
 *            Based on existing code of dfu-util and testlibusb
 *
 * \warning   does only work on little endian machines!
 *
 * \author    Christoph Zimmermann bfh.ch
 * \date      2009-1-23 first version
 * \date      2009-8-25 fixed some little bugs. option --device works now,
 *                      counts connected GECKO3 boards now correct.

28			`* \brief simple small helper tool for GECKO3COM`
29			`*`
30			`* with this tool you can set the serial number, hw revision`
31			`* and FPGA type of a GECKO3COM driven device.`
32			`* mainly this is the GECKO3main but the firmware could be`
33			`* used on other boards. \n`
34			`* Based on existing code of dfu-util and testlibusb`
35			`*`
36			`* \warning does only work on little endian machines!`
37			`*`
38			`* \author Christoph Zimmermann bfh.ch`
39			`* \date 2009-1-23 first version`
40			`* \date 2009-8-25 fixed some little bugs. option --device works now,`
41			`* counts connected GECKO3 boards now correct.`
