I have a USB button that I am trying to setup so that when clicked, it triggers the home screen to transition to a video. I have the project all setup in brightsign author, but when the button is clicked, nothing happens. One potential issue is that I may not be using the "Specify USB input" field correctly. Any ideas why the button is not triggering the event? Below is a picture of my current setup. This project is for a Brightsign Model XD1033. Thank you!
