You could trace a bit more, e.g. GST_DEBUG="v4l2*:7" and try to find
more details. Note that from the following trace, it says that the
driver refuse to start streaming with generic i/o error. Last time I had
this generic error, I found that the USB bandwidth was not sufficient.
Lowering resolution or framerate was the only solution.
