I just recently got the pixhawk, i plugged it into the computer and the device drivers installed fine i then went to mission planner to try upload Arduplane to it. A dialog box appeared to unplug then replug it back in i did this and then says "Connecting" in the corner and after 10min it says "Error no response received from board". So now i followed the instuctions on this page and it still would not upload. I reinstalled the drivers for it with no luck and i even tried to upload the firmware with Mission Planner 2.0 still with no luck every time it gets as far as replugging in the pixhawk and then it stops. I have used to most recent driver files and it still will not work.
