Hi, I'm new to this forum but have been building a set of switches and buttons with arduino by using the com ports and joystick functionality of FSUIPC. At first I used FSX and the aerosoft A320 bundle and everything was great (Also using FSUIPC v4), buy then i changed to P3D, Aerosoft's professional A320 and FSUIPC v5 and problems started. In the beginning I thought it was random. My plane would turn off at any point of the flight, sometimes twice if I was in the ground on the first shutdown. But then I've managed to find out that I can replicate the error when I plug a new device to the computer. The FSUIPC log will say "HID USB device reconnected: re-initialising FSUIPC connections" and in that point it wont read the actual state of my joystick switches. (For example, if the engine switches on the joystick are ON, FSUIPC will read all switches as off after the "sudden" reconnection, until I move any of the switches, and now it would read all the actual states of the switches, but at this point the plane is already off with several switches moved to zero positions) The thing is, to summarize, sometimes my PC (and i've tried on different PCs, reinstall windows and p3d and everything) reconnects all USB devices randomly on FSUIPC (not on actual windows since I dont listen to the connection sound) Maybe the device that reconnects are the bluetooth ones, but it doesn't matter, what I need to get working is to stop this "reconnection" of FSUIPC every time a new device is recognized by my computer.
