In one example, when the mass storage function as described above is activated (step S530 of FIG. 4a), the three fields "bDeviceClass" F6101, "bDeviceSubClass" F6102, and "bDeviceProtocol" F6103 are set to a reserved value" 0x00". In another example, when the virtual port function as described above is activated (step S530 of FIG. 4a), the described fields F6101 to F6103 are respectively set to reserved values "0x02", "0x00", and "0x00". ". The configuration description element describes the configuration information of the coupled mobile phone. Figure 6b is a schematic diagram of a data structure of a configuration description element comprising eight fields according to an example of an embodiment of the present invention. The mobile phone can provide more than one configuration description element to the computer host, and each configuration description element can describe multiple interfaces. The high-speed configuration description element is identical to the configuration description element and describes the configuration information of the high-speed device. Figure 6c is a schematic diagram of a data structure of a high-speed configuration descriptor including nine fields according to an embodiment of the present invention, comprising eight fields. The interface description unit describes the specific interface in the configuration unit. Figure 6d is a schematic diagram of a data structure of an exemplary interface description unit according to an embodiment of the present invention, comprising nine fields. In one example, when the mass storage function as described above is activated (step S530 of FIG. 4a), the three fields "bInterfaceSubClass" F6201, "bInterfaceSubClass" F6202 and "bInterfaceProtocol" F6203 are respectively set to reserved values" 0x08", "0x06" and "0x50". The interface and device description elements described above indicate that the coupled mobile phone support supports a standard mass storage interface. In another example, when the described virtual port functionality is enabled (step S530 of Figure 4a), two interface descriptors must be provided. In one of the interface description elements, the fields F6201 to F6203 are respectively set to the reserved values "0x02", "0x02" and "0x00", and in another interface description element, the fields F6201 to F6203 are respectively set to The values "0x0a", "0x00" and "0x00" are reserved. The interface and device description elements described above indicate that the coupled mobile phone supports two standard virtual interface interfaces. Each interface description element can be associated with zero to more endpoint description elements. The endpoint description element contains information required by the host computer to determine the bandwidth requirements of each endpoint.

The universal serial bus data lines D+ and D- are connected between the universal serial bus controller 810 and the external universal serial bus connector 830 via resistors R81 and R82 to match the characteristic impedance of 90 Ω ± 15%. Those skilled in the art will appreciate that matched resistors R81 and R82 are disposed relative to the universal serial bus controller 810, closer to the external universal serial bus connector 830. The data line D+ can be pulled up to V _USB (3.3V) through resistor R83, which is preferably 1.5KΩ. The regulator 850 is disposed between the power source VPP and the resistor R83, and selectively converts or does not convert VPP to V _USB according to the enable signal USB_EN. When the enable signal USB_EN is set to high (that is, the universal bus bar device is enabled), the regulator 850 converts the VPP to V _USB , so that the host computer (eg, FIG. 2a, FIG. 130) recognizes the high-speed universal serial bus device (eg, Figure 2a, Figure 200) has been inserted. On the other hand, when the enable signal USB_EN is set to low (ie, the universal bus bar device is not enabled), the regulator 850 does not convert the VPP to V _USB , so that the host computer (eg, FIG. 2a, FIG. 130) recognizes the original connection. The high speed universal serial bus arrangement (eg, Figure 2a, 200) has been removed. Referring to step S540 of FIG. 4a and step S970 of FIG. 4b, a connection signal can be generated by setting the enable signal USB_EN to be high. Referring to step S940 of FIG. 4b, the connection signal can be turned off by setting the enable signal USB_EN to be low.

Anyone familiar with the art can understand that when a mobile phone is connected to a host computer by inserting a universal serial bus device, the connection signal is transmitted to the host computer, and some software modules are configured to be activated, and when When the mobile phone is removed from the host computer by pulling out the universal serial bus device, the closed connection signal is transmitted to the host computer, and the specific software module is configured to stop. Step S920 of FIG. 4, when the user directly pulls out the universal serial bus device of the mobile phone from the host computer, or when the user presses the button corresponding to the soft key "Close Connection" 720 corresponding to FIG. When the device is not actually pulled out, the shutdown operation is determined, and the shutdown connection signal is transmitted to the host computer to stop certain software modules and close the previously determined function. Step S920 of FIG. 4b, when the user directly pulls out and then reinserts the universal serial bus device of the mobile phone, or when the user presses the button corresponding to the soft key "reselection function" 730 of FIG. When unplugged and reinserted, the reselection operation is determined. The off connection signal is transmitted to the host computer to stop some software modules to close the previously determined function, and then the connection signal is transmitted to the host computer. Used to launch other software modules to start another function.

The data line D- can be pulled up to V _USB (3.3V) through resistor R83, which is preferably 1.5KΩ. When the enable signal USB_EN is set to high (that is, the universal bus bar device is enabled), the regulator 850 converts the VPP to V _USB , and then the host computer (eg, FIG. 2a, FIG. 130) recognizes the low-speed universal serial bus device (eg, Figure 2a, Figure 200) has been inserted. Conversely, when the enable signal USB_EN is set to low (ie, the universal busbar device is not enabled), the regulator 850 does not convert the VPP to V _USB , and then the host computer (eg, FIG. 2a, FIG. 130) recognizes the previously connected low-speed universal. The serial bus arrangement (as in Figure 2a, Figure 200) has been removed.
