What is USB 1.0?

USB 1.0 or Universal Serial Bus version 1.0 is the very first USB technology version introduced in January 1996. The reason for introducing USB is to standardize the wired cable connectivity for the input and output devices.

After introducing the USB 1.1 to the market by USB Type A or USB Type B, the legacy connectivity ports which we used in the old mouse and keyboards got a threat of extinction due to the faster and user friendly cables.


USB or Universal Serial Bus uses serial protocol to pass data. Unlike the Serial Ports USB does have only four connectivity lines in a single port. Two connectivity lines are to transfer data and the other two connectivity lines to transfer electricity.

 The first generation USB or the Generation 1.0 USB ports were not that popular and they had needed driver to installed by a Mini CD to function USB ports. With the time and by USB 2.0 only the USB became really a plug and play connectivity type.

In the version 1.0 USB there only two port types, which was USB type A and USB type B. Both the port types does have two different shapes in it.

When the USB introduced in 1996, the protocol had the speed of 1.5Mbit/s low speed and 12Mbit/s full speed transfer rate.
