Abstract
The present invention provides a bi-directional electronic device with USB interface, comprising a two-in-one USB connector and a USB OTG controller. The two-in-one USB controller has a USB standard-A type male connector and a USB standard-B type female controller, disposed in housing; the two-in-one USB controller is designed so that only the selected USB standard-A type male connector and the USB standard-B type controller can be used for plugging in. The USB OTG controller determines the operation mode of the bi-directional electronic device with the USB interface based on the plugging position of the USB standard-A type male controller and the USB standard-B type controller of the two-in-one controller.
