The USB connection seems to provide a view on the controller screen, and a way to depress controls.
With the eventual capability to exchange configuration files with the MGen, it might be possible to automate some procedures.
And this would probably also give access to the APN shutter control, along with the nice random offset feature.
But there are still many ifs (and I need to push other changes related to v4l2, it's been a long time since I could test with clear skies here).
