First, you should know about USB 2.0, and for your information it is Universal Serial Bus standard. This standard was developed to describe communication protocols, together with connectors and cables, between electronic devices and computers like scanners and printers. As the total number of devices reproduced in types and quantity, the USB port was accepted as the central connection portal.
Electronic devices such as PDAs, smartphones, smartphones, tablets and video game consoles can without any difficulty connect to laptops or computers with these ports. It is allowing communication and recharging thereby changing the requirement of power chargers and adapters.
Today, USB 2.0 getting popularity in the market to connect two different devices. Most laptops and computers include minimum two USB 2.0 ports, and few contain even more, due to the growing requirement for more ports to connect devices of users. Here are some differences between USB 1.0, USB 2.0 and USB 3.0
- USB 2.0 is an upgraded version of 1.0 and 3.0 is more advance to 2.0
- USB 2.0 is faster than 1.0 (480 MBPS) and USB 3.0 and more faster than 2.0 (4Gbps)
1.0 has two operation modes, but 2.0 adds an additional one
3.0 is recently coming to the electronic market, but it seems to be a great perfection in speed.
1.0 is the creative iteration that was often referred to as just “USB”, but 2.0 changes the definition of speed and now what’s more discuss about USB 3.0 speed.
Now you can find the 2.0 ports on almost all current laptop and desktop computers (Mac and Windows). With a high bandwidth of 480Mb/second (which is 40 times faster!) this new USB standard is far more appropriate for audio devices compare to the original USB.

You can without any difficulty plug USB 1.1 devices into ports of 2.0 and they will work as they generally have (at 1.1 speeds).
The 2.0 version even has considerably improved its controlling of asynchronous MIDI data to decrease timing irregularities.
Generally the 2.0 supply up to 500 mA and add more power when required and preserve power when the device is linked but idling.
In its place of one-sided communication, version 2.0 can handle one way of data at any time.
