USB3.1 port and Type-C port on the iPhone

In the industry, the USB3.0 interface is colored blue to distinguish it from the black color of the USB2.0 interface. Asus has already introduced motherboards with standard Type-A USB3.1 ports, which are distinguished from USB3.0 in A blue-green color. Although the USB Association does not specify the color of USB3.1, it will be inevitable to distinguish by color.

The author reiterates that Type-C interface and USB3.1 standard were introduced almost at the same time, and the specification of Type-C is indeed formulated in accordance with USB3.1. Therefore, USB3.1 can certainly be made as type-C, but type-C ≠USB3.1: For example, the Nokia N1 tablet uses the USB2.0 specification Type-C interface, while the Asus Z97-K/USB3.1 uses the standard USB3.1 Type-A interface.
