What is the micro USB pinout? I need it for shutter release.

The Samsung Remote Viewfinder does not allow control of Movie shutter. I purchased the camera to use its CCD capability for Aerial videos to eliminate rolling shutter issues. The camera will only take 20 minute videos so I need a way to trigger the shutter from the cockpit.

If it is possible to remotely trigger the shutter through the USB port I would be in business.
