[Allstar Digital] All-star to Dstar and back

What is the best way to get this done? I have an xlxd reflector with a dv3000 and many dstar boards. What is the best way to get this done? I would rather have software not software and hardware. I know I will probably need the dv3000 board. But just need the piece to connect the two together. I just don't want to have to run a usb fob to a dstar board.
