We are trying to get DirectShow work with USB video capture devices like this. The code simply adds the capture source's filter (capFilter) in the capture graph and then connects it to VMR9 renderer already added to the graph.

captureGraph.RenderStream(null, MediaType.Video, capFilter, null, vmr9);

At present, everything runs without throwing any exception, but the output is just black. I checked the capture source's output in GraphStudio, but it also resulted in the same black output.
