It controls the board from the USB port. You may have to change your interconnections for it to work on your board. In the files area is the firmware that makes the PIC look like a serial port to Windows. The firmware also has a bootstrap loader which allows all future firmware updates to be done via the USB port rather than the ISP lines and a separate programmer.
