Following the pan-tilt tutorial with Arduino the schematic says that the camera should be powered through the red cable of the 4 pin connection using a clean 5V power supply and says nothing about powering the camera with USB.
But the jevois documentations says that powering the camera using a USB connection is always required.
What is correct? This is the jevois tutorial I am referencing: http://jevois.org/tutorials/UserPanTilt.html
