Universal serial bus hub and control method thereof

Abstract

A universal serial bus (USB) hub includes a first downstream facing port (DFP), an extensible host controller interface (xHCI), a second downstream facing port (DFP), a router, and an upstream facing port (UFP). The first downstream facing port (DFP) is configured to receive a first universal serial bus (USB) data. The extensible host controller interface (xHCI) is configured to convert the first universal serial bus (USB) data into a peripheral component interconnection express (PCIe) data. The second downstream facing port (DFP) is configured to receive a second universal serial bus (USB) data. The router is configured to convert the peripheral component interconnection express (PCIe) data into a first tunneling data, and convert the second universal serial bus (USB) data into a second tunneling data. The upstream facing port (UFP) is configured to output the first tunneling data and the second tunneling data.
