Abstract
A hub including a first connection interface, a second connection interface, and a signal bypass circuit is provided. The first connection interface has a first pin to receive a first connection message. The second connection interface has a second pin to transmit the first connection message. The signal bypass circuit is coupled to the first pin and the second pin to decide whether to bypass the first pin and the second pin based on the first connection message.
Claims3
A hub, comprising:
- a first universal serial bus (USB) c-type interface comprising a first channel configuration pin configured to receive a first connection message;
- a first transmission/receipt circuit coupled to the first USB c-type interface and receiving the first connection message to provide a connection configuration signal;
- a second universal serial bus (USB) c-type interface comprising a second channel configuration pin configured to transmit the first connection message;
- a second transmission/receipt circuit coupled to the second channel configuration pin and configured to restore the connection configuration signal to the first connection message;
- a controlling circuit coupled to the first transmission/receipt circuit and the second transmission/receipt circuit to receive the connection configuration signal and providing a transmission switch signal based on the connection configuration signal;
- and
- a signal bypass circuit coupled between the first transmission/receipt circuit and the second transmission/receipt circuit in serial, and coupled to the controlling circuit to decide whether to bypass the first transmission/receipt circuit and the second transmission/receipt circuit based on the connection configuration signal and the transmission switch signal.
