Embodiment Construction

[0022] The invention aims at the composite device and overcomes the problem that the existing data card network device driver cannot be used after being unplugged and plugged in under certain circumstances. For example, for a data card that coexists with storage devices, if the user opens the file in the storage device and then pulls out the data card, when the user inserts it again, the network device of the data card cannot be used, and a yellow exclamation mark will appear in the device manager. The file is not closed, the operating system will not send removal notices to CDs and other devices when the card is removed, the driver cannot delete the device, the USB composite device driver will enumerate the same device when the card is inserted again, and the network device driver cannot be initialized, causing the device to fail. use.

[0023] The technical scheme of the invention includes a data card network device driver, a USB composite device driver and a virtual bus dri...

Abstract

The invention provides a wireless communication terminal and a driving method thereof. The wireless communication terminal comprises a network device drive, a USB (universal serial bus) composite device drive and a virtual bus drive; a UBS composite device creates and manages a virtual bus device; a virtual bus device drive is added between the network device drive and the USB composite device drive, the virtual bus drive creates and manages network device on the virtual bus drive, and transmits a USB request and response between the network device drive and the USB composite device drive. A virtual bus drive is added at a drive lower layer of the current data card to isolate the network device of the data card and the USB composite device of an operation system, the creation and management of the network device is completely finished by the virtual bus device without the participation of the USB composite device of the operation system; the operation is more flexible; furthermore, the virtual bus drive can recognize various abnormal conditions of the virtual bus drive and the network device and effectively process the abnormal conditions.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a wireless communication terminal and a driving method thereof. Background technique [0002] Data card is a common wireless terminal product, which can provide users with high-speed network data services and outstanding mobility. The data card can be connected to the computer through an interface such as USB or PCMCIA. The simplest data card can be just a modem device or a network device (collectively referred to as network device), and more complex ones can include serial ports, TV modems, memory cards or optical discs, etc. [0003] Most users use the Windows operating system today, and the use of data cards on Windows requires the support of driver software, and Windows itself provides a variety of general device drivers. Taking a USB data card as an example, for a data card that only includes a modem device or a network device, Windows provides a USB...
