My Zoom H2 when used as a USB devices introduces 0 controls, but I can
monitor from it and record. I'm still not able to fix the latency issue I'm
having there, or the fact that I hear the clean signal (going in to the
computer) together with the processed one which is coming out from JACK. I
just gave up because it wasn't my intention to make it do anything, just
curious to see how it worked.
