Ok, I got the source code and I an build it with the free Visual C++.Net
Express 2005.

I do not have a good HID device to test this port. Anyway, just running
the first example here. It seems to work.

The HID device is PICkit 2 (http://www.microchip.com/pickit2). I am
using the libusb-win32 device driver.
