The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines. For USB 2.0 the voltage supplied by low-powered hub ports is 4.4 V to 5.25 V

Is The USB port can supply power for device?
Yes, a USB port can supply a small amount of power for attached devices.
Is there any way to control the voltage output on usb?
The output voltage available at a USB port is controlled by the regulator in the computers power supply. It is fixed, you can not change or control it. The maximum current which should be drawn from a USB2 port is 500mA, from a USB3 port it can (I believe) be up to 850mA.
If you have a video camera and you have a wire that says DC IN what do you plug that in to on your computer or do you leave it out?
