How to tell what type of USB connector you have by color?

Have you ever wondered why some USB Ports or connectors have different colors? If so, then that is why you are reading this post.  

Basically the difference in colors is all about specifications (1.x, 2.x, 3.x, etc), but here are the details

1. White Color 

This type of the USB connector is known as USB 1.x Plug. This was the first release of USB and that was in 1996. There was another version of this specification in 1998. Although the white colors indicates that it is USB 1, some are USB 2 compatible. The USB 1 is obviously slow and can transfer about 12Mb/s only! 

2. Black Color

This is the second generation of USB connectors. It was released in Apr-2000. This specification is also known as Hi-Speed as it is capable of  transferring  up to 480 Mb/s and it is compatible with the older version (USB 1)

3. Blue Color

This is the third generation (USB 3 and 3.1) and was released in  Nov-2008. This specification is known with its super speed, up to 3.2Gb/s and its compatible with USB 2. Then the USB 3.1 was introduced in Jan-2013 and this specification is capable of 7.2 Gbit/s. This specification is also known as SuperSpeed+

That is all. Thanks for your time :)
