A universal serial bus (USB) type C transmission line includes a host-to-host bridge, a first multiplexer, and a second multiplexer. When a first device and a second device are coupled to the first multiplexer and the second multiplexer respectively, the first multiplexer determines whether the first device is a host or a slave device and the second multiplexer determines whether the second device is another host or another slave device, and the first device optionally communicates with the second device through the host-to-host bridge, the first multiplexer, and the second multiplexer, or through the first multiplexer and the second multiplexer according to determination results of the first multiplexer and the second multiplexer.

A power delivery controller includes a detection unit, a regulation unit, and a control unit. The detection unit has a detection pin and an enable pin, wherein the detection pin is used for detecting a power delivery consumer device. The regulation unit is coupled to the detection unit, wherein when the detection pin detects the power delivery consumer device, the detection unit is used for turning on the regulation unit through the enable pin, and after the regulation unit is turned on, the regulation unit generates an internal voltage. The control unit is coupled to the regulation unit for providing power to the power delivery consumer device according to the internal voltage. When the detection pin fails to detect the power delivery consumer device, the regulation unit is turned off.

A universal power delivery cable includes a first connector, a second connector, and a power delivery controller. The first connector is used for coupling a host, wherein the host has a power delivery function. The second connector is used for coupling an electronic device. When the first connector is coupled the host, the second connector is coupled the electronic device, and the electronic device does not have the power delivery function, the power delivery controller makes the electronic device imitate to have the power delivery function. After the power delivery controller makes the electronic device imitate to have the power delivery function, the host charges the electronic device according to a specification of the power delivery function and a specification of the electronic device.

A USB 3.0 host with low power consumption includes a super speed circuit, a non-super speed circuit, and a control module. The super speed circuit is used for transmitting data at a first transmission speed. A default state of the super speed circuit is turning-off. The non-super speed circuit is used for transmitting data at a second transmission speed, a third transmission speed, or a fourth transmission speed. The first transmission speed is faster than the second transmission speed, the third transmission speed, and the fourth transmission speed. The control module is used for detecting whether a USB peripheral device is connected to the USB 3.0 host, and controlling turning-on and turning-off of the super speed circuit.

A USB 3.0 compatible host with low power consumption includes a super speed circuit, a non-super speed circuit, and a control module. The super speed circuit transmits data at a first transmission speed and the non-super speed circuit transmits data at a second transmission speed, a third transmission speed, or a fourth transmission speed wherein the first transmission speed is faster than the second transmission speed, the third transmission speed, and the fourth transmission speed. Further, the control module is coupled to the super speed circuit and the non-super speed circuit for determining to turn on or off the super speed circuit of the USB 3.0 compatible host, during the USB 3.0 compatible host being connected to a USB 3.0 compatible peripheral device, based on whether transmission data quantity between the USB 3.0 compatible host and the USB 3.0 compatible peripheral device is greater than a predetermined value.

A bridge includes a Peripheral Component Interconnect Express interface supporting at least two lanes, an Extensible Host Controller Interface, and a Universal Serial Bus 3.0 root hub. The Peripheral Component Interconnect Express interface is used for coupling to a host. Each lane of the at least two lanes provides a highest data transmission speed. The Extensible Host Controller Interface is coupled to the Peripheral Component Interconnect Express interface for storing data transmitted by the Peripheral Component Interconnect Express interface. The Universal Serial Bus 3.0 root hub includes a first controller and a second controller. The first controller and the second controller are used for controlling data transmission of four ports, and a highest data transmission speed provided by each port of the four ports is not more than the highest data transmission speed provided by the lane.
