Hi , i have a little problem with my teensy 3.5, i am a newbie and i am learning arduino. I wrote a program with my teensy for using it as a joystick for x-plane 11 and it works very well ! (thanks to the developpers of the librairies and the board ! ). My problem is : i have to unplug it before turning on my pc.As long as my teensy is plugged my pc (windows 7) don't want to launch. any idea ?
