In our daily life, various electronic devices such as computers, mobile phones, game consoles, etc. require data cables whether they charge or transmit data, but there are all kinds of data cables. These data cables have a standard called USB standard.

In our daily life, various electronic devices such as computers, mobile phones, game consoles, etc. require data cables whether they charge or transmit data, but there are all kinds of data cables. These data cables have a standard called USB standard.

Since the release of the USB 1.0 standard by the USB Implementers Forum organization (USB-IF) in 1996, the USB standard has experienced the development of multiple versions of USB 1.0 released in 1996, the USB 2.0 released in 2000, the USB 3.0 released in 2008, the USB 3.1 released in 2013, and the 3.2 version of USB 3.2 in 2017. In 2019, the USB-IF organization released the latest USB 4.0 standard, bringing new standard specifications to the USB interface.

After the USB naming change in 2019, the final naming is:

USB 1.0 changed to USB2.0 Low-Speed

USB 1.1 changed to USB2.0 Full-Speed

USB 2.0 changed to USB2.0 High-Speed

USB 3.0 changed to USB 3.2 Gen1

USB 3.1 changed to USB 3.2 Gen2×1

USB 3.2 changed to USB 3.2 Gen2×2

So after the new naming, some manufacturers advertised using the USB 3.2 standard, maybe the USB 3.0 standard, but the new naming is USB 3.2 Gen1. The main advantage of

USB 4.0 is the maximum speed of

40 Gbps, compatible with Thunderbolt 3 devices, if you use the USB 4.0 port to transmit video and data simultaneously, the port will allocate bandwidth accordingly. The biggest obstacle to the popularity of USB 4.0 is that the manufacturing cost is too high.

Then I will introduce to you the interface

USB has so many protocols, and there are various interfaces. The interfaces are mainly divided into three types: standard USB interface, Mini USB interface and Micro USB interface.

standard USB interface is divided into Type-A and Type-B interfaces. Type-A and Type-B can be divided into USB 2.0 and USB 3.0 standard USB interfaces according to the supported USB standards. Depending on the color of the interface, it is easy to distinguish whether the interface supports USB 2.0 (white) or USB 3.0 (blue).

Mini USB interfaces are divided into Mini -A and Mini -B.

Micro USB interfaces are divided into Micro-A, Micro-B and Micro-B (3.0).

The earliest mobile phone interface used the Micro-B interface. The Type-C interface is a USB interface developed in recent years and has been widely used in mobile phones and computers. The latest USB4.0 protocol is mainly the Type-C interface. However, the Type-C interface we often use is USB 3.0, USB 3.1, and USB 3.2 interfaces. You must distinguish it clearly when purchasing.
