Embodiment 1

[0051] figure 2 It is the flow chart of self-starting and self-installation when the data card of the present invention is inserted into the PC for the first time, and the specific steps are as follows:

[0052] Step 210, the data card is inserted into the PC for the first time, the PC detects the insertion of the data card, and enters the USB device enumeration process.

[0053] Step 220, during the enumeration process, the data card reports a device descriptor, wherein the device descriptor includes the VID and PID number of the data card.

[0054] Step 230, the PC searches the registry for the driver according to the VID and PID number. Since the driver and software for the data card have not been installed on the PC, the system cannot find the driver corresponding to the PID and VID number in the registry. In this case, the PC will send the configuration command of configuration 1 (set config 1) to the data card.

[0055] Step 240, after receiving the set config 1 confi...

Embodiment 2

[0064] Such as image 3 As shown, when the PC has installed the driver and related software, when the data card is inserted again, it will not be started in the form of CDROM, but will be configured directly in the configuration mode saved in the registry. The specific steps are as follows:

[0065] In step 310, the data card is inserted into the PC and powered on to enter the enumeration process.

[0066] Step 320, during the enumeration process, the data card reports the device descriptor, which contains the VID and PID numbers of the data card.

[0067] Step 330, the PC searches for the driver in the registry according to the VID and PID number, taking the data card with vid 19d2 and pid 00 as an example, find the DWORD variable UsbConfigNum in the vid_19d2&pid_00xx subkey, and pass its value through set config The command is sent to the data card. If the value of UsbConfigNum is 2, the PC sends the set config 2 configuration command to the data card.

[0068] Step 340, a...

Embodiment 3

[0072] Such as Figure 4 As shown, the user can dynamically switch the configuration of the data card during use. Taking switching from configuration 2 to configuration 1 as an example, the specific steps are as follows:

[0073] Step 410, the user opens the configuration switching interface in the terminal.

[0074] Step 420, assuming that the current data card is working in configuration 2, and the user needs to switch to configuration 1, at this time, the button "Switch to CDROM" in the configuration switching interface can be clicked.

[0075] Step 430, in the event response of the button, the PC sends a setconfig 0 command to the data card through the USB interface.

[0076] Step 440, after the data card receives the set config 0 command, according to the configuration in Table 1, uninstall all the interface devices in the existing configuration 2, and change the status of the USB device to the ADDRESSED (address setting) status, and the data card will re-enter enumera...

Abstract

The invention provides a self-starting method of a universal serial bus data card, comprising the following steps: when the fact that the data card is inserted is detected by a terminal, judging whether the drive of the data card is installed on the terminal; if not, identifying the data card as an optical disk, reading the optical disk content from the data card for installing the drive; and if so, adopting the drive of the data card to load the data card. The invention also discloses a self-starting system of the universal serial bus data card. By utilizing the method and the system in the invention, the data card has rapid and stable startup.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a self-starting method and system for a USB (Universal Serial Interface) data card. Background technique [0002] With the popularization of notebook computers, users have an increasing demand for notebook wireless Internet access. The most common way for notebooks to access the Internet wirelessly is to use wifi (wireless broadband), but the wifi coverage rate is very low, and it is almost difficult to find a suitable wifi access point in public places, which greatly limits the user's demand for wireless data services. The birth of 3G network has really made it possible to surf the Internet anytime and anywhere, and the wireless data card with USB interface has become one of the best choices for notebook computer users to surf the Internet. At present, China Mobile has started to build a TD-SCDMA (Time Division Synchronous Code Division Multiple Access, referred to as TD) ne...
