USB with a 4-pin (USB3.0 standard for the 9-pin) plug as a standard plug, daisy chain can be used to connect all the peripherals, up to 127 external devices can be connected, and will not lose bandwidth. USB requires the host hardware, operating system and peripherals in three areas to support work. The current motherboards are generally used to support the USB function of the control chipset, the motherboard is also installed USB interface socket, and in addition to the backplane socket, the motherboard USB interface is also reserved for USB pin, you can connect through the connection The front of the chassis as a front USB interface to facilitate the use of (Note that the wiring should carefully read the motherboard manual and according to map connection, do not connect the wrong equipment damage). And USB interface can also be through a dedicated USB cable to achieve dual-machine interconnection, and can be extended through the Hub more interfaces. USB has a high transmission speed (USB1.1 is 12Mbps, USB2.0 is 480Mbps, USB3.0 is 5Gbps), easy to use, support hot swap, flexible connection, independent power supply, etc., you can connect the mouse, keyboard, Scanners, camcorders, flash drives, MP3 players, mobile phones, digital cameras, mobile hard drives, external floppy drive, USB card, ADSL Modem, Cable Modem, etc., almost all external devices.
