USB Remote confirmed to work with 4.5V; however, the port on the camera is a combined USB/Video Out port which has nonstandard 5pin USB configuration. To get the remote working, I wired my switch and voltage using the female side of a dissected USB extenstion cable (male to female full size USB) and connected the female end to the white Cannon-Supplied USB cable that came with the camera.
