Anyone using a Thrustmaster Warthog w/ MFS?

Hi and good morning

I think Im too stupid to understand
I have installed Joystick Gremling and vjoy (ok)
So I can load the xml file (ok)
BUT
everything looks the same. I only see 1 vitual Joystrick…nothng looks like a configuration, all windows are the same
???
And 2nd (what I dont nderstand)…how can I switch using the MSFS software between the real hardware (the yellow bindings) and the virtual bindings (green / red)?
Can anyone help me?

Thank you

Best,
Lutz
