That's exactly what the device does. It sits there and listens to both A and B ports. Whichever one sends data becomes the active port and the other port is blocked until both ports are quiet. All you have to do is send a command to the "printer" (or whatever device you have at the far end) when the app launches, and the Switch senses activity on that port and makes it the active one. Unless your device is constantly sending a stream of data, it should work.
