Hi. That's how I was testing them. Although I was setting up cam 1 and then starting it, followed by setting up camera 2 and then starting it.

It occurred to me that if it's the start that is causing the problem, then the start and stop could be moved into the source switching loop, and the whole open/setup/close could be left out of the loop. This may shorten the time taken to switch cameras to a less noticeable pause.

Since I'm just discovering all this code, what is the purpose of the "notify" code in the error case? The original only checks the notification status of USB 0. Does this indicate when the camera is up and running again?
