Processing system and method for connecting a remote usb device automatically

Abstract

A processing system and method for connecting to a remote USB device automatically. The processing system and method provide a user computer to be connected to or disconnected from a USB device via a network system and a USB server connected to the USB device. In the beginning, the user computer finds a USB device for the user computer from the USB server via the network system; when detecting that the user computer issues request messages, the USB server connects the user computer with the USB device, and the USB device executes corresponding services according to the request messages issued by the user computer; in the last, after detecting that the USB device has finished the corresponding services according to the request messages issued by the user computer, the USB server is enabled to disconnect the user computer from the USB device.

What is claimed is: 
     
         1 . A processing method for connecting a remote USB device automatically, for allowing a user computer to be connected to or disconnected from a USB device via a network system and a USB server connected to the USB device, the processing method comprising the following steps of:
 (1) via the user computer finding a USB device usable for the user computer from the USB server via the network system;   (2) when detecting that the user computer issues request messages, having the user computer detect a connection status of the USB device via the USB server according to the request messages, and then having the USB server connect the user computer with the USB device, if a detection result of the connection status indicates an idle status, proceeding to step (3); and if the detection result of the connection status indicates a busy status, keeping detecting the connection status of the USB device, until the detection result of the connection status indicates the idle status, then proceeding to step (3);   (3) having the USB device execute corresponding services according to the request messages issued by the user computer; and   (4) after detecting that the USB device has finished the corresponding services according to the request messages issued by the user computer, enabling the USB server to disconnect the user computer from the USB device.   
     
     
         2 . The processing method of  claim 1 , wherein in step (1), having the user computer find a USB device usable for the user computer from the USB server via the network system is according to a fact that device information of the USB device connected to the USB server are stored in the USB server, and a consistent USB device is found for the user computer after the device information are compared with the driver information stored in the user computer. 
     
     
         3 . The processing method of  claim 2 , wherein in step (1) the USB device uses the device information to identify each different USB device if there are more than one devices with the same model. 
     
     
         4 . The processing method of  claim 1 , wherein before step (1) is executed, the USB server checks a user identification account of the user computer that finds via the network system the USB device for the user computer. 
     
     
         5 . The processing method of  claim 1 , wherein before having the user computer detect a connection status of a USB device via the USB driver according to the request messages of step (2) is executed, the USB server checks whether time when the user computer issues request messages is consistent with that when a USB device is in use. 
     
     
         6 . The processing method of  claim 1 , wherein before having the USB connect the user computer with the USB device of step (2) is executed, the USB server records time when the user computer is connected to the USB device. 
     
     
         7 . The processing method of  claim 1 , wherein before having the USB server disconnect the user computer from a USB device of step (4) is executed, the USB server records time when the user computer is not connected to the USB device. 
     
     
         8 . The processing method of  claim 1 , wherein in step (4), detecting that all the issued request messages have finished the corresponding services is based on that the a queue area of the user computer is detected to be clear.
