FIELD OF THE INVENTION The present invention is a universal serial bus hub, especially a universal serial bus hub with a cursor control function. ^ Background of the invention Universal Serial Bus (USB) has gradually become the main port type of personal computers, because it can simplify the connection between external peripheral devices and the host computer, and then use a transmission line Various peripheral devices are connected in parallel to solve the problem of a large number of wires around the back of the mainframe of a personal computer. It can also 'plug in various peripheral devices at any time without restarting or installing, so many necessary peripheral components (Such as keyboard, mouse, trackball, etc.) Most have gradually developed a form that can support the universal serial bus, and many emerging peripheral components (such as digital cameras, scanners, digital cameras, etc.) have also been universal The sexual serial bus is used as the standard interface as the main way to connect with a personal computer. Please refer to the first figure, which is a schematic diagram of a general-purpose serial bus hub (USB Hub) circuit block diagram, wherein the upstream port (UpStreaiI1 port) is a type B connector ll (type B Connector), through a universal The universal serial bus cable (USB cable) is connected to the universal serial bus port (not shown) on the motherboard of the personal computer (not shown in the figure), and via a universal serial bus The role of the hub controller 12 will be

498268 V. Description of the invention (2) Control multiple downstream ports (d0wnstreain port) completed by type A connector 13 for signal transmission actions, and then provide multiple external peripheral devices for connection. At present, the hardware type of the universal serial bus hub (USB Hub) is 'except that the manufacturer has integrated the manufacturing in any place of its casing at the time of design'. Generally, the installation method for self-assembly or upgrade is available. It is divided into the following types: (a) The interface card is installed on the back of the main body of the personal computer. The appearance is as shown in the second figure (a). The type A connector 21 (type A Connector) is used. Outside exposed on the back of the host casing. (b) placed on the user's desktop _ with a hardware type appearance as shown in the second figure (b), and 'connected to a personal computer with a universal serial bus connection cable 2 2 (USB cable)' Type A connector 2l (type a Connector) is 1 for other components to connect. Since the back of the mainframe of the personal computer is originally missing, and there are a lot of peripheral signal cables used here for connection, if the second figure (a) is used, its connector is installed in the mainframe shell. The back of the body will not only cause difficulties for the user, but will also occupy space of other interface cards. And if the type in the second figure (b) will occupy the increasingly crowded desktop space of users, how to solve the lack of the conventional technology mentioned above is one of the main purposes of developing this case. Summary of invention

This cable is connected to several lower port connectors. The control device is also controlled by the downstream port connector, which is in series. The case is a type that includes: a line and the personal port connector universal serializer and a plurality of and a plurality of lower 'electrically connected to the universal serial connector common line to connect the line to the upstream bus line The upstream port connector with cursor control function is connected through the computer motherboard to be used for 'for multiple peripheral bus hub controllers' downstream port connectors, and the signals between the swim port connectors are in the universal series. The bus-bus hub controls the upstream port connector and the host computer motherboard to perform the port connector, the downstream controllers, and the cursor. It is a universal serial signal device for electrical connection to control the transmission action. The hub is controlled by the universal number transmission; the port connector control device collects the serial and serial transmission of the bus; the multiple connection; the upstream and upstream ports; a cursor controller, and the serial bus and a shell, The universal co-construction is in its rank. According to the above idea, the universal serial bus hub with cursor control function System control means to perform a track ball device. According to the above-mentioned concept, the cursor control device in a universal tandem bus with a cursor control function is a touch panel device. Simple schema

The solution to this case can be obtained through the following diagrams and detailed descriptions. Figure • It is a universal serial bus hub (USB Hub) power
