The code below is already written when the application is closed. The important thing is that the phidget control panel does not work even if the unity editor is open, not the phidget project. ------------------------------------------------------ void OnApplicationQuit() { if (Application.isEditor)...

I am trying to use phidget 1046_0B (Bridge 4-input) in Unity.

However, an open error occurs in the phidget control panel even when the Unity editor is open without running in the Unity editor.

Of course, even if you run Unity, an open error is issued saying that Unity is using it.
