Hi, Now that the ARC Pro has been released (at least in Denmark) and I have had the pleasure to play with it, I must say you should be very proud with this addition to your product line, thank you! Earlier on it has been stated that the USB port is intented for 3. party development of RMS. My question now is when do you plan to release the documentation for the USB port communication protocol? (so that we can make your product even more cool) Best regards, Jesper
