[0004] As can be seen from the above, in the existing method for initializing a USB device, the staff knows that the USB device has been initialized through a dialog box displayed on the computer screen. The staff cannot distinguish which initialized USB device corresponds to the dialog box displayed on the computer screen. Only after all the USB devices have been initialized can they unplug the USB device and insert a new USB device. When the computer only When there is a single USB interface, the staff needs to initialize the USB devices one by one, and the operation is cumbersome. After one USB device is initialized, the next USB device can be initialized. When the number of USB devices to be initialized is large, the above method It takes a long time to complete the initialization of the batch of USB devices, making the initialization speed and work efficiency low

The invention discloses a method for initializing universal serial bus (USB) devices. The method comprises the following steps: connecting a USB concentrator connected with USB devices to be initialized to an initializing device; starting an initializing program in the initializing device; monitoring whether the USB devices are inserted or not by the initializing program, if so, respectively establishing threads for the USB devices and initializing the USB devices corresponding to the threads, and if not, continuing to monitoring; detecting whether all the USB devices on the USB concentrator finish initialization or not, and if so, informing a user that the initializing processes of the USB devices are finished and turning off the connection of the USB concentrator and the initializing device. The invention also discloses a system for initializing the USB devices. By applying the invention, the initializing device can parallel initialize the USB devices, effectively improve the initializing speed and the working efficiency and reduce the initializing time of the USB devices.
Description
technical field [0001] The invention relates to a universal serial bus (USB, Universal Serial Band) device initialization technology, in particular to a method and system for initializing a USB device. Background technique [0002] The USB interface is the most commonly used standard interface on computers at present. External devices of the computer, such as USB keyboard, USB mouse, digital camera, mobile hard disk, USB key (USB Key) card, etc., communicate with the computer through the USB interface. Among them, the main functions of the above-mentioned external devices (hereinafter referred to as USB devices) are provided by the smart card chip or smart card chip module contained in it. Taking the information security device USB Key as an example, it will support the public key system (PKI, Public KeyInfrastructure) The smart card is combined with the smart card reader to improve the security performance of the USB Key. [0003] Before the USB device is put into use, th...
