USB Cable USB Interface Technology Details
Jul 09, 2018


    Since the USB version V0.7 was released on November 11, 1994, the USB version has experienced many years of development and has been developed into the 3.1 version, becoming the standard expansion interface in current computers. The main board currently uses USB1.1 and USB2.0, and each USB version is very compatible. USB uses a 4-pin (USB 3.0 standard 9-pin) plug as the standard plug. In daisy-chain mode, all peripherals can be connected and up to 127 external devices can be connected without losing bandwidth. USB requires the support of the host hardware, operating system, and peripherals to work. Current motherboards generally use a control chipset that supports the USB function, and a USB interface socket is also mounted on the motherboard, and in addition to the backplane socket, the mainboard

A USB pin is also reserved, which can be connected to the front of the chassis as a front USB port for easy use. (Note that you must carefully read the motherboard manual and connect it as shown in the diagram. Do not connect it incorrectly to damage the device.) . Moreover, the USB interface can also realize dual-machine interconnection through a dedicated USB connection line, and can expand more interfaces through the Hub. USB has a fast transmission speed (USB1.1 is 12Mbps, USB2.0 is 480Mbps, and USB3.0 is 5Gbps). It is easy to use, supports hot-swappable, flexible connection, and independent power supply, and can be connected to a mouse, keyboard, and printer. Scanners, cameras, flash drives, MP3 players, cell phones, digital cameras, mobile hard drives, external optical floppy drives, USB network cards, ADSL Modem, Cable Modem, etc. Almost all external devices.

In theory, the USB interface can be used to connect up to 127 peripherals such as a mouse, modem, and keyboard. Since its introduction in 1996, USB has succeeded in replacing serial and parallel ports and has become one of the necessary interfaces for today's personal computers and a large number of smart devices.
