I had just received my Erle-Rover. The OS it is running is frambuesa. I connected all the necessary connections when I first got it and the RC controller controlled only the steering. Upon research I found that I need to install the APM Planner and download the firmware and install the correct parameters. Following the instructions, the first step is to connect the erle-brain to my PC and download the necessary drivers so that the Planner can detect the correct port. The issue is that my PC, and two other PC's that I've tried won't detect the Erle-Brain3. Am I doing something wrong? I can provide any necessary information that could help lead me to the solution.
