USB 2.0 allows for quicker file transfers than USB 1.0.

Universal Serial Bus (USB) controllers are small pieces of hardware that allow your computer to load connections through your USB ports. USB 2.0 is a complete overhaul of the USB input and output protocol allowing for higher speed than its older counterpart. The goal of this new serial bus is to broaden the range of external peripherals that you can plug into a computer. USB 2.0 uses a raw data rate of 480 Mbps, which is 40 times faster than its preceding interface. Peripheral devices that use legacy ports such as PS/2 serial and parallel ports require USB functionality. All USB drivers include a set of drivers that install after the device is inserted into a USB port.
