Invention Description () Therefore, based on the above-mentioned M custom printer port as the data transmission structure between the two computer hosts, The rate of occurrence of crashes or crashes is relatively high, and it is not suitable for the combination of real-time data input between a laptop computer host and a desktop bravery host. Therefore, it is widely used in regulations today. USB (UNIVERSAL SERIAL B US, universal serial bus), although it has the advantages of plug and play, and high data transmission bandwidth, but in the USB architecture (TOPOLOGY), a HOST CONTROLLER plus It is composed of several DEV ICEs, so that the USB room is limited by the fact that the HOST CONTROLLER cannot support each other, and cannot be used as a data link between the host computer and the host computer (HOST TO HOST). 〉 Therefore, the main purpose of the present invention is to provide a host-to-host The USB orange device is designed to enable two or more computer hosts with a USB interface to obtain a device with a bridge connection function between the USB interfaces of the two computer hosts. It is used for USB interface connection between computer hosts and can be executed by remote control commands from any computer host to execute a large amount of data. Another purpose of this creation is to provide a host-to-host USB bridge device. The interconnection of the devices with the bridge connection function can make the interfaces between the multiple computer hosts form a connection, and form a structure of USB data transmission between multiple computer hosts.

Description of the invention () Please refer to _ three pictures, as shown in the first picture and the second picture of the USB bridge device 100 of the present invention, the structure of the actual application The actual appearance is not limited to any type, and the one shown in the third figure is made of a smaller ASIC or its equivalent circuit device, which is housed in a USB cable 缵 300. The structure can be covered in any part of the USB cable 缵 300. The state of the preferred embodiment shown in the third figure is placed at the end of the USB cable. In the USB connector 310, similarly, the other USB connector 310 'can also be used for receiving the USB bridge device 100 of the present invention, so that the USB bridge device 100 of the present invention can be more convenient and convenient in application. Take up space, in other words, just use a USB connection cable with a USB bridge device 100 inside as shown in the third picture. 300 can complete the USB data transmission link structure between the two computer mainframes 200 and 200 * as shown in the second picture. Please cooperate with the fourth picture, as shown in the first picture to the blue picture above. The invented USB connection device 100 operates in a remote control mode for transmitting data horizontally. Among them, the data transmission control commands and data transmission between the computer host 200 and 200, are basically written and controlled by the CW terminal. (CONTROL WRIT E) and bulk data write xBW (bulk WRITE), and the receiving end responds by interrupt input (INTERRUPT IN) I and data bulk BR (BULK READ). These operations are performed horizontally and by 檷. It is used to show and say: the order issuing and data transmission process in the application examples of the diagrams under the Ming M. And in the USB data transmission link structure shown in the fourth _, it is displayed by the host computer 200 to The remote control mode transmits the state of the data to the host computer 200 through the USB bridge device 100 of the present invention.

In the data transmission structure, the data transmission or the data transmission operation is controlled by the computer host 200 to write the CW data transmission control command to the first-in-first-out control command transmission device in the USB connection device 100. 30 and 30 ', and before the control command is sent out, the first-in-first-out control command input device 30 and 30' cannot accept any command, so when the brain host 20 < The first-in-first-out control command transmitters 30 and 30 * fetch data from the register 20 and input control commands, and issue an interrupt input I command to the bit. At the other end of the host computer 200 ', at this time, the interrupt input I control command is issued, so that the host computer 200' is in a state of being controlled and ready to receive data. When the host computer 200 'of the controlled terminal is in a state ready to receive data, the host computer 200 of the remote terminal starts to input the serial data of the "1" and "0" first-in-first-out mode, respectively. A large number of data are written into the BW mode to send data to the first-in-first-out data transmitters 40 and 40 'of the USB bridge device 100, and the first-in-first-out data transmitters 40 and 40 are buffered, and then executed by M. The data is most concealed in the BR mode, and the Fu is input to the host computer 200 'of the controlled end. And the first-in-first-out MU data converters 40 and 40' provide functions such as buffers (BUFFER) at this time. It can take turns for the computer mainframes 200 and 200 'to write and read data respectively, and achieve the invention. The invention can achieve MUSB through the remote control of the host 200 or 200' at one end.

A7 ___B7_ V. Description of the Invention () Purpose. Please refer to the fifth figure again for the present invention The USB bridging device 100 is applied to the operation mode of the remote end between the Chunao host 200 and 200 'to read the data of the controlled end or broadcast the event, that is, the host computer 200 of the remote control side sends control to the USB bridging device 100 Write the control command of CW, and then save the USB eaves device 100 temporarily, and then send an interrupt input I to the host computer 200 of the controlled end, so that the host computer 200 'of the controlled end writes a large amount of data again. The method of entering BW is to write (fu lose) the data and the project to be extracted to the USB bridge device 100, and then flush the data from the USB bridge device 100, and then the USB connection device 100 will use the actual data. Read out the BR method, and transmit the data or project to the host computer 200 of the remote end, so as to achieve the purpose of remote control of USB data or project by the host of the present invention. This is the USB bridge device 100 of the present invention, which is used to write a file or data to the remote control terminal between the computer's mainframe 200 and 200 '. Access is not a simple case or data loss, but refers to the brain on the remote end. The machine 200 is synchronously written into the resources or files. For example, a real-time online software program or online discussion data is written on the host computer 200 to the controlled host 200 *. The operation mode is shown in the fourth figure. The remote control transmits the real material horizontal type and the remote control data shown in the fifth figure. The comprehensive type of the horizontal type is taken. That is, the host computer 200 on the remote end sends the USB bridge device 100 into the control command and writes the CW control command. After being temporarily stored by the USB bridging device 100, it will send an interrupt input I to the host computer of the controlled terminal 200 '' to make the controlled brain computer 200 ready to receive data. , And then controlled computer-1 0-This paper size is applicable to China National Sample Rate (CNS) A4 specification (210X297 mm) L ----- ^ ---------- install- -„-11 Order ------ ^ line (please read the note on the back of this page first) The Ministry of Economic Affairs Central # 局 局 贝 工 consuming cooperatives printed A7 B7 V. Description of the invention () Host 200 ' Send a control command to write control CW to the USB bridge device 100. After the USB bridge device 100 is temporarily stored and buffered, the data and the right plan are sent by the USB After the bridging device 100 is flushed, the USB bridging device 100 sends an interrupt input I to the host computer 200 of the remote end, so that the host computer 200 writes the data or rights in the BW mode in a large amount of data. The file is sent to the USB bridge device 100. After the USB bridge device 100 is balanced, a large amount of data is extracted from the USB bridge device 100 and the BR method is used to send data or files to the host computer 200 of the controlled end. In order to achieve the purpose of the M host of the present invention, one of the hosts remotely controls USB data or writes data to the other party. As shown in the fourth to sixth figures above, the USB bridge device 100 of the present invention is applied to various application examples between the host computer 200 and the host computer 200 '.
