The original standard USB 1.0 has a transfer rate of about 1.5Mbps. This means if you record a 2GB video and transfer via USB cable to a USB 1.0 connection it is gonna take some time. You only need to be aware of this if you have an older computer.
Time marches on and USB 2.0 is the next way of connectivity. The transfer rate is about 480Mbps so that data moves a lot faster than a USB 1.0 connection.

But those pesky scientists and engineers have a need for speed. so there now is USB 3.0 with a transfer rate of 4.8Gbps. You can tell the difference between a USB 3.0 port and the earlier ports by the color blue that appears inside the connector. The port is backward compatible with USB 2.0.
So here is the deal:
If you have a USB 3.0 port and the supporting cable use it to transfer video from your device to the computer. It will go much faster.
If you a USB 3.0 port but your device was designed to transfer at USB 2.0 then you don't gain any advantages in using the higher speed port.You can use a USB 2.0 cable with the faster port but it will transfer at USB 2.0 speeds.
If you have an old computer you might want to consider using the memory card you recorded the video on to transfer data. It would be faster than using the USB 1.0 cable.
