The USB hub 300 is coupled between the first host 100 and the second host 200, and the USB hub 300 receives a first data D1 according to a network protocol, such as retrieving the first data D1 from the Internet. As shown in fig. 1, the USB hub device 300 includes a first uplink port 302a, a second uplink port 302b, a first downlink port 304a, a second downlink port 304b, at least two third downlink ports 304c, a host bridge device 308, and a network control module (network control module) 306. In one embodiment, the USB hub device 300 is integrated into the first host 100 or is independently disposed outside the first host 100 and the second host 200. In one embodiment, the network control module 306 is connected to the Internet 204, for example. In one embodiment, the network control module 306 is used to support the transmission of network data (e.g., messages transmitted via the Ethernet protocol) between the host and the peripheral equipment, and can convert the network data into USB messages (e.g., messages transmitted via the USB protocol) for transmission between the two hosts or between the two hosts and the Internet 204 via the USB hub 300. In one embodiment, the first host is an all-in-one (AIO) computer having a USB port, but not limited thereto, a computer system having a USB port may also be used as the first host. The second host is, for example, a notebook computer, but is not limited thereto, and a computer system having a USB port may also be used as the second host, for example, a handheld electronic device.

As shown in FIG. 1, the first uplink port 302a is coupled to the first host 100 according to a communication protocol. The second uplink port 302b is coupled to the second host 200 according to the communication protocol. The first downlink port 304a is coupled to the first uplink port 302a. The second downlink port 304b is coupled to the first uplink port 302a. The host bridge device 308 is coupled to the second uplink port 302b and the first downlink port 304a to establish communication between the first host 100 and the second host 200, for example, data transmission and reception between the first host 100 and the second host 200 via the first uplink port, the first downlink port 304a, the host bridge device 308 and the second uplink port 302 b. The network control module 306 is coupled to the second downstream port 304b, and the network control module 306 receives the first data D1 according to the network protocol.

Wherein the network control module 306 converts the first data D1 into a second data D2 according to the communication protocol, the first host 100 receives the second data D2 through the first path PA1 and transmits the second data D2 to the second host 200 through the second path PA2. In another embodiment, the second host 200 receives the second data D2 from the network control module 306 through the second path PA2 and the first path PA 1.

In one embodiment, the first host 100 and the second host 200 can display the second data at the same time, for example, after the first host 100 retrieves the second data D2, the second data D2 is displayed on the first host 100, and after the second host 200 retrieves the second data D2, the second data D2 is displayed on the second host 200.

As shown in fig. 1, in one embodiment, the USB hub further includes two third downstream ports 304c respectively coupled to the first upstream port 302a, the two third downstream ports 304c are used to connect a mouse (not shown) and a keyboard (not shown) for the mouse and the keyboard to operate the first host 100 and the second host 200 together, i.e. the mouse and the keyboard can switch between the first host 100 and the second host 200.
