• USB 3.0 is also used as SuperSpeed USB. Generally, laptop manufacturers use the SuperSpeed USB logo to differentiate the port. You can find the ss mark along with the USB logo, which looks something like the following image: It may have a SS before the port identifier Port Color Identify USB 3.0 Port in Laptop - Check Color The USB 3.0 port should have blue color inside the port whereas USB 2.0 has either black or white inside the port. It can happen with both the ‘male’ as well as the ‘female’ port.

• The USB 3.0 port will have a blue "tongue" and the USB 2.0 port will have a black "tongue".
