I’m using Radiomaster Zorro RC. I connected it (as joystick), started Mission Planner and SITL, then I enable it using Joystick user control, after that I was able to use it and it works fine, but after I clicked Disable it didn’t turn off, MP continued to read Joystick chanels with wrong configuration.
The only solution I’ve found to prevent such behaviour is to connect joystick when MP is already started
