The method of difference client/server directivity is to be illustrated in down.Because the running of system is based on a client/server model, so when the client of cable 16 is inserted into client computer 12, should automatically perform client application 122, and when the server end of cable 16 is inserted into server computer 14, should automatically perform server-side application 142.ASIC 162 is that a kind of PC installs PC (point-to-point), and does not have any directivity in essence.Therefore, a hardware element or circuit are set in the coupling arrangement 16 with the granter tropism.A guide to visitors program (pilot program) is set in the coupling arrangement 16, and it can distinguish client and server end direction based on the information that is provided in hardware circuit or element, and can call out corresponding client-side program or server.Two kinds of methods in order to the difference direction are to be illustrated in down.
Referring to Fig. 6, first method is used a hardware element that is arranged in the coupling arrangement 16, that is usb hub 164.ASIC 162 is connected to the downstream port of usb hub 164, and the upstream port of usb hub 164 waits to be connected to client computer 12.Referring to Fig. 7, when the client of coupling arrangement 16 is inserted into client computer 12, it is general usb hub to 12, one of clients that coupling arrangement is lifted two USB devices of row, and another is high capacity storage device (client high capacity storage device) (step S71).If the user opens the device manager (Device Manager) of client 12 when the client of cable 16 is inserted into client 12, then the user will see a usb hub and USB high capacity storage device.When the server end of USB cable 16 was inserted into server computer 14, the USB cable was lifted row one high capacity storage devices (server end high capacity storage device) to server (step S71).
Each high capacity storage device stores guide to visitors program, in order to difference client/server directivity, and these guide to visitors programs are performed (step S72) after connecting each computing machine.When each guide to visitors program of execution, whether the operation system of computer that its inquiry is connected has specific USB high capacity storage device to come across the downstream port of specific usb hub, and this is judged (step S73 and S74) by USB VID of the predefined of USB device (ID of manufacturer) and USB PID (product IDs).If judged result is "Yes" (" Y " among " Y " among the step S73 and the step S74), determine that then this side is a client, and client application is to be loaded on the computing machine (client) that is connected and to be performed (step S75) from USB high capacity storage device.If judged result is "No" (" N " among the step S73 or " N " among the step S74), determine that then this side is a server end, and server application is to be loaded on the computing machine (server) that is connected and to be performed (step S76) from USB high capacity storage device.
Referring to Fig. 8, second method is used the hardware circuit be arranged in the coupling arrangement 16, that is universal input and output (general purpose I/O, GPIO) circuit 166.GPIO 166 is connected to the client of ASIC 162, and for ASIC 162 provides a basis, in order to lift the different USB high capacity storage device of row to client 12 and server 14.Referring to Fig. 7, when the client of cable 16 and server end are inserted into client 12 with server 14 (step S91) respectively, if ASIC 162 determines that a direction has the GPIO 166 (" Y " among the step S92) that is connected to it, then this direction is a client, and ASIC enumerates the USB high capacity storage device that comprises a character string to the computing machine (client) (step S93) that is connected, and this character string has predetermined specific device information.If ASIC 162 determines that a direction does not have GPIO 166 (" N " among the step S92), then this direction is a server end, and the ASIC act is listed as a USB high capacity storage device of the character string that does not contain the predetermined specific device information of tool to the computing machine (server) (step S94) that is connected.This act row can make guide to visitors program decision server or client-side to.
The guide to visitors program in each high capacity storage device of being stored in is loaded on the computing machine (client or server) that is connected and goes up and be performed (step S95).Whether guide to visitors program inquiring operation system of computer has the USB high capacity storage device (step S96) of a character string that comprises predetermined peculiar device information.If determine that then this side is a client, and client application is to be loaded on the computing machine (client) that is connected and to be performed (step S97) from USB high capacity storage device.If not, determine that then this side is a server end, and server application is to be loaded on the computing machine (server) that is connected and to be performed (step S98) from USB high capacity storage device.
About the alternative method of above-mentioned two kinds of methods, directivity may be arranged among the ASIC 162 itself.In other words, but not point-to-point device, ASIC 162 may have two different directions or side.The server end of ASIC 162 is with the USB high capacity storage device of emulation storage server end application program, and the client of ASIC stores emulation the USB high capacity storage device of client application.
Because application program is stored in the usb file transmission yarn, and the usb file transmission yarn is modeled into and automatically performs storage device (for example floppy drive, Winchester disk drive or CD-ROM CD-ROM drive etc.), so usb file transmission yarn of the present invention can automatically perform file transfer and needn't install driver and program.For the user, when file transfer can be performed automatically, and needn't install driver and program in arbitrary computing machine the time between two computing machines, the application process of usb file transmission yarn provides the plug and play ability.
All videos and keyboard/mouse data are that (Application Program Interface API) obtains, and is wrapped into package then and transfers to opposite side for application program user's interface via operating system.In opposite side, be from the package that is received, to take out data by software, and data are sent to operating system, use the desktop of reaching between client and server and share and Long-distance Control.
According to the system of one embodiment of the invention, be to use hardware circuit or element so that guide to visitors program (pilot program) difference client (control side) and server end (Be Controlled side) again.Then, the guide to visitors call program is treated clients corresponding or the server-side application by corresponding computing machine execution.
