Dear Pete,
thank you so much for all your observations, remarks and recommendations and instructions.
Just to clarify. Ihave installed:
1. Rudder Pedals from Thrustmaster, plug and play, called T Rudder.
There are two functions used: Rudder and Brakes
2. I have 8 Arcazes installed from Simple Solutions.
I am controlling app. 150 - 200 buttons and switches with them. And a number of LED outputs
I am also controlling 4 analog devices - 2 throttle levers, spoilers and flaps. 3 with glare 1, 1 with glare2
3. I have 5 Arduino MEGA installed.
With them I am controlling app. 50 buttons and switches, some LED outputs and all of my 7 segment displays.
4. I have installed the new T.a320 sidestick from thrustmaster that creates the problem.
I can see all buttons reacting in the windoes controller, but not in the fsuipc controller.
It is the same situation when I switch on or off the controller in FSX / option / controllers
So everything is working well except this new side stick.
With that in mind I was wondering ... "never change a running system ..."
But if you think that this file desparately needs a clean up, I could go through the exercise.
I guess the file was messed up so much, because recently, I had a Windows 10 crash and had to rebuild
everything base od the back ups that I had.
Would another option be to delete the modules folder and let it get created by a new fsuipc download?
Again, thank you very much for your time to help me.
Attached is a little picture of my cockpit.
Best Regads
