Because it seems you are the only user having this issue, is difficult to help you. I suggest you divide the problem. Fly the plane only with 5 hardware commands. Then if every is find add 5 more programmed to your hardware device. Until you find a CTD. That way you will know which command is affecting the pluging. I believe is a command. Not hardware, because I have used warthog joystick that has 2 usb, peddals with another usb, and trackir without any problem. So divide and you will win. I think you will be surprised managing the plane without those hardware is not difficult and unconfortable until you find your problem
