Confused about how to identify the USB 3.0 interface on your computer? PHP editor Zimo brings you a detailed answer to this question. This article will delve into the characteristics of USB 3.0 and provide you with an easy way to identify its interface. Continue reading to reveal the mystery of the USB 3.0 interface and easily solve your doubts!
When looking at the USB interface in a bright place, you usually have to turn the notebook sideways and look at the number of copper pieces under the USB. There are five small copper pieces in front of USB3.0 (look carefully, just to the left) Very close outside), with four large copper pieces at the back.
USB2.0 only has four large copper pieces at the back. (Of course, most manufacturers distinguish between the two. As others have said, USB3.0 is blue, while USB2.0 is black)
USB 3.0 is a new generation of USB interface. It is characterized by a very fast transmission rate. It can theoretically reach 5Gbps, which is 10 times faster than the common 480Mbps High Speed USB (referred to as USB 2.0) and surpasses it in all aspects. IEEE 1394 and eSATA. The appearance is basically the same as an ordinary USB interface, and it is compatible with USB 2.0 and USB 1.1 devices.
USB 3.0 is the latest USB specification, which was initiated by big companies such as Intel. USB 2.0 has been widely recognized by PC manufacturers, and the interface has become a must-have interface for hardware manufacturers. It will be clear
if you look at the motherboards commonly used at home.
1. If your system is win10, you can right-click the "Computer" icon on the desktop,
2. Then left-click "Properties" in the shortcut menu that comes out, and then In the system properties page that comes out, left-click the device "Manager",
3. In the device manager list that comes out, click on "Universal Serial Bus Controller",
4. Check inside to see if there is a device with the words "USB3.0 Extended Host Controller". If so, it means that your host supports USB3.0. There is another simple way to check your If all the USB interfaces on the computer host (on the motherboard) have blue USB interfaces, there may be one or several, which generally means that your host supports USB3.0.
The USB 3.0 interface is usually blue, which is different from 2.0. The speed of 3.0 is faster than the speed of 2. The premise is that the speed of the 3.0 device will be improved when it is connected to the 3.0 port. In addition 3.0 is compatible with 2.0, but the speed is still the speed of 2.0
The type-c interface and the usb-c interface are actually the same thing. The full name of the USB-C interface is USB Type-C.
Type-C is a connection interface of USB interface. It can be inserted into both sides regardless of the front and back. The size is about 8.3mm×2.5mm. Like other interfaces, it supports USB standard charging, data transmission and display. Output and other functions. Type-C was developed by the USB Implementers Forum and became popular after receiving support from Apple, Intel, Microsoft and other manufacturers in 2014.
The USB-C interface is called USB Type-C and is a next-generation USB 3.0 interface. Its highlights are slimmer design, faster transmission speed (up to 10Gbps), and stronger power transmission. (Up to 100W). In addition, the USB-C interface also supports double-sided insertion. You can plug in the front and back at will. It is more advanced than USB2.0/USB3.0
USB3.0 data cables are the same, and those from mobile phones and mobile hard drives can be mixed.
1. The USB 3.0 interface is a unified standard and is divided into different interface types, but as long as the interface type is the same, it can be used universally.
2. In fact, with USB 2.0, mobile phones and hard drives can also be used interchangeably. For example, the data cable of a mobile phone that also uses the mini usb interface can be used in common with the mobile hard disk cable at that time.
3. For Android phones with USB 3.0 interface, if you use an ordinary macro USB interface data cable, just connect it directly to the larger part of the right half of the interface. This is also universally compatible.
USB3.0 is two-way downward compatible.
After the 3.0 interface is plugged into the 2.0/1.1/1.0 device, the transmission follows the old specifications. After the 3.0 device is plugged into the 2.0/1.1/1.0 interface, the transmission follows the old specifications. It can be used, but the speed is slow!It’s useless to have a 3.0 interface. There will be no peripherals that support USB 3.0 in a short time. Even for mobile hard drives, the speed bottleneck is not in the interface, but in the internal transmission rate
It is impossible to convert the USB2.0 interface into a USB3.0 interface.
USB2.0 is lower than USB3.0 in terms of power supply capacity and transmission speed. You cannot convert a low-speed port into a high-speed port. USB3.0 devices can be used on the USB2.0 interface.It can be achieved by extending the USB3.0 to USB card. It is more troublesome for laptops without USB3.0. For desktops, it is simple. Buy a PCIE to USB3.0 expansion card and plug it into the computer motherboard. It can be used in a few seconds. Ten yuan a card,
