Embodiment Construction

[0026] In order to make the features and advantages of the present invention more comprehensible, preferred embodiments are listed below, together with the accompanying drawings, as follows:

[0027] figure 1 It is a schematic diagram of the transmission system of the present invention. As shown in the figure, the transmission system 100 includes electronic devices 110 , 120 and a transmission line 130 . The electronic device 110 performs power and data transmission with the electronic device 120 through the transmission line 130 . Since the electronic device 120 is disposed outside the electronic device 110, the electronic device 120 may be called an external electronic device.

[0028] The transmission line 130 has connection ports 131 and 132 for coupling to the connection ports 111 and 121 of the electronic devices 110 and 120 . The present invention does not limit the types of the connection ports 111 and 121 . In this embodiment, the types of the connection ports 111...

Abstract

The invention provides an electronic device including a connection port, a control unit, a switching unit and a chip unit. The connection port is used for coupling with an external electronic device. The external electronic device provides data information. When a trigger accident occurs, the control unit enables a control signal. When the control signal is enabled, the switching unit closes a first path for transmitting data information. When the control signal is not enabled, a second path is closed for transmitting data information. When the chip unit receives data information through the first path, the electronic device is operated in a first device mode. When the chip unit receives data information through a second path, the electronic device operates in a host mode. In the device mode, the electronic device is controlled by the external device. In the host mode, the electronic device controls the external electronic device. In the embodiment of the invention, even the electronic device only has a standard USB connection port, it can still operates in the host mode and the device mode.

Description

technical field [0001] The present invention relates to an electronic device, in particular to an electronic device operable in a host mode or a device mode. Background technique [0002] With the advancement of technology, there are more and more types and functions of electronic devices. Generally speaking, a host device usually has many connection ports for coupling many electronic devices. Among various connection ports, a universal serial bus (Universal Serial Bus; USB) supports hot-swapping and plug-and-play. Therefore, most host devices are provided with USB connection ports. [0003] However, since there are many types of USB connection ports, many different USB connection ports are configured on the host device, resulting in inconsistent appearance. Furthermore, if the host device can only be configured with a standard USB connection port, the host device cannot enjoy the functions provided by other USB connection ports.
