And its internal data transmission method. [Prior Art] With the advancement of information technology, portable electronic products and computer peripheral devices with various functions have been developed in response to the convenience and needs of people's lives. For example, ': Memory Cards and Card Readers of various specifications, Common Names (Fiash Disk), Portable Hard Disks, Digital Cameras (Digital Camera) ), MP3 player (MP3 Player), and even various types of computer mouse (M〇use), keyboard (Keyboard), printer (Printer) and so on. However, the above-mentioned electronic products or computer peripheral devices need to be connected to a computer host for information transmission or exchange, and a universal serial bus used for exchanging information between various products of different specifications and a computer host (Universal) SeHal O Bus (USB) is the current mainstream data communication protocol, so people can easily access file data on any computer host with a USB interface. However, USB still encounters some troubles and inconveniences in real life use, especially when the number of USB interfaces provided by the host computer is insufficient. For example, the general notebook computer (Notebook) is limited by the size. Usually only available, two USB ports 'If the user wants to use more than two USB adapters (D〇ngle) to connect to the notebook (for example: same time to use Bluetooth transmission, external keyboard, external mouse And the pen drive), it is necessary to use the multiple USB attached 3 201028860, and the inter-connector takes turns to perform the plugging and unplugging action, resulting in inconvenience in use. Therefore, many electronics manufacturers are working hard to integrate multiple USB adapters into a single USB connector to allow users to use the limited USB interface more flexibly.

Consultation 1 refers to the second 0, 4 and 5 diagrams. 'The above paragraph 2 (4 1) is wrapped with (5) at least including terminal code (5 G), - event instruction and - data coding (5 2 ) The terminal code (5 Q ) is used for the main controller (\1 2)_ the unit controller (丄丄丄), and the data is programmed (5 2) for the material to be transmitted/transmitted, and The state of the main controller (112) or the unit controller (ill) is determined according to the event instruction (5丨). The above-mentioned step zen 4 (4 3) uses the serial data channel (s DA) and the serial clock channel (sc L) high and low potential conversion to start the data packet (5) transmission system is already familiar to the skilled person The general technology of the specific implementation has been widely applied to a serial communication bus using technology of the internal integrated circuit, and therefore, it will not be described here. Therefore, by the above method, the present invention is different from the traditional physical hub to connect a plurality of functional devices to achieve a USB function with a plurality of functions, but to encapsulate the data sent by different functional devices by using a packet format. The unified interface is communicated with the USB of the host by the serial interface, so it can achieve the functions of independent circuit, simplified Zhao circuit and proper utilization of system resources. The present invention is disclosed in the above preferred embodiments. However, it is not intended to limit the present invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. The patent protection scope of the invention shall be based on the definition of the scope of the patent application attached to the specification.
