I have uploaded my file to Microchip forum so that everyone can download the source code and the build instruction. The compiled application is included as well. To use it, you still need to download libusb-win32 device driver or the libusb-win32 filter driver (us together with Microchip driver) from the libusb-win32 website. The URL is http://forum.microchip.com/tm.asp?m=106426.
