V. Creation Description (l) < Technical Field of New Type > This creation relates to a hub, especially a hub that is suitable for an electronic device and can support a USB interface and a Bluetooth interface. < Prior art > The Universal Serial Bus (USB) has the advantage of being ready to use and can be used to connect electronic devices such as personal computers and peripheral devices, printers, or mobile phones to For today's personal computers, the USB interface is the core interface. The USB port is expandable and its data transfer speed has been increasing. However, in order to maintain the compatibility between the upgraded version and the existing USB specifications, the system still needs two An independent host controller (Host Controller), one corresponding to USB 1.1, the other corresponding to USB 2.0, and routing logic (Routing Logic) to transfer the port to the corresponding host controller, and meet the USB 2 · Specification devices must be connected to a USB 2. hub device in order to be able to exert its performance, and it is best to maintain the same cables and connectors as USB 1 · 1; the recently emerging concept of Bluetooth technology is to Eliminate the "wire" system during transmission between various electronic products, "replace wired with wireless", and use low-power, low-cost wireless RF transceiver technology to allow two electronic devices or devices to Can between the wireless transmission, the transmission offers free unlimited space. It can be seen that if USB is the "wired connection" standard for computers and their peripheral devices, Bluetooth will be one of the standards for "wireless transmission" and can be used as a "PAN / Personal Area Network" ). However, it is possible to combine both USB and Bluetooth technology

M242872 V. Creation Instructions (2) There are very few products. As for desktop computers, since desktop computers cannot communicate with other Bluetooth-supported electronic devices, they cannot provide a convenient wireless network connection. The reason why desktop computers do not generally have built-in Bluetooth support is that the installation of Bluetooth must connect the wireless interface card to the motherboard, so the host must be disassembled and installed, which is too much for users. Difficult, it can not be installed as easily as changing the graphics card or hard disk. In addition, in order to avoid the trouble of installing the Bluetooth wireless interface card mentioned above, there are also people who use a USB interface Bluetooth device with a USB interface to directly plug into the computer. However, such a USB interface Bluetooth device will occupy the USB connector of the computer and must be separately Purchase, therefore, not only because the USB connector of the computer is occupied and the external resources are reduced, other hubs must be used for expansion, but also the cost of purchasing a USB interface Bluetooth device will be increased. Therefore, due to the problems of the above-mentioned conventional technologies, only electronic devices such as notebook computers, desktop computers, LCD computers, servers, workstations, palmtop computers, personal digital assistants, and mobile phones can choose to use USB or Bluetooth. One of the budding interfaces cannot have both capabilities such as plug and play, unlimited expansion, and wireless transmission, which will cause inconvenience and difficulty in use, and will not meet the needs of the market. Therefore, how to provide a hub that can be used in electronic devices at the same time with a low-cost and easy-to-use USB interface and Bluetooth interface is a problem that needs to be studied and overcome. | < New Content > In order to solve the shortcomings of the above-mentioned conventional technologies, the main purpose of this creation is to
