Good question...a lot of people with notice this when they get the VR home!! The camera connects in the back but the 2 USB ports in the front is kind of tricky. The VR processor will use one so the only other one is for charging the DS4 controller. Now, since you have 2 motion controllers, you are going to have to charge both of them (temporarily removing the processor while not in use) and charge them BEFORE playing obviously. BB does sell the stand the chargers both the DS4 and motion controllers plus has a stand for the headset. This is probably a MUST have with the USB situation on the older PS4. The new PS4 Pro will actually have 3.
