So I have a Devo 7 (uses the 3.5mm audio plug), and I have a Mac. What do I need to get this connected? I'm sure I need some sort of 3.5mm audio plug to USB conversion, but not sure which one. Any help would be greatly appreciated.
Generally most people have luck using a "22-in-1" universal flight simulator USB dongle.
