ABSTRACT:
A USB cable connects to a USB connector in an electrical/electronic product and a USB connector in a separate type USB unit so that a USB controller and a conversion circuit are connected. The conversion circuit converts a USB signal into an external interface signal which is transmitted to and received from a peripheral device. The external interface signal is transmitted to and received from the peripheral device through an external interface connector. The minimum number of interface connector is selected from various external interface connectors through which the external interface signal is transmitted to and received from the peripheral device. By connecting expansion connectors5and6in a USB unit and those in another USB unit, the USB signal is transmitted and received between the USB unit and another USB unit.
