I have tried repeatedly to assign joystick buttons in the PMDG keyboard assignment menu like autothrottle d/c, TOGA, however it doesnt seem to recognize my joystick buttons when i push them, however it can recognize my normal keyboard keys.My joystick buttons can be assigned and work in the default MSFS menu, however the features which i want to assign are not located there, but in the PMDG keyboard assignment menu.Thanks in advance

Hi,AFAIK this is NOT possible - I also tried this myself. But you can assign a key to a function (e.g. "T" for TOGA) and then assign a joystick button for this specific key in your game software that came with your controller.
