USB is a universal external interface for a variety of peripheral devices such as keyboard, mouse, modem, printer, microphone, speaker, camera or scanner. USB knows only one connector type for all devices on the host side, so that confusion of interfaces is impossible. USB has also quickly established itself as the standard interface in industry. The transfer rates of USB 3.0 of up to 5GBit/s are ideal for the operation of many very demanding industrial applications.
