Problems solved by technology

[0006] The above-mentioned peripheral device access state detection method has the problem that the detection is not real-time enough, and the failure of a detection command does not prove that the peripheral device has been separated from the computer, so it is necessary to wait for a certain number of unsuccessful attempts to prove that the device has been separated from the computer. , especially for devices that use AT commands to communicate, because a command itself will time out for a certain period of time, so the judgment is even less timely

Embodiment Construction

[0025] The core idea of ​​the present invention is: in view of the wide variety of peripheral devices of the current computer host computer and the relatively flexible access characteristics, the detection of the access status of the peripheral devices is not timely enough, which may lead to abnormalities in the application programs of the peripheral devices, and even affect the computer. The host's operating system. After the peripheral device is connected to the state computer, an application program needs to be installed to support the use of the peripheral device. When the application program is installed, the computer operating system will create a registry subkey for the peripheral device under the corresponding registry key , when the peripheral device is connected to or separated from the computer host, the operating system will modify the registry sub-item of the peripheral device. The present invention uses the detection thread to detect the change of the registry sub...

Abstract

The invention discloses a method for checking the access status of peripheral devices and relates to a peripheral device checking technique. To solve the problem that peripheral devices can not be checked in time currently, the invention adopts the following proposal: a method for checking the access status of peripheral devices. A sub-key of peripheral devices is added under the registry of the operating system of the host, and a thread is provided to checking the sub-key of peripheral devices. Triggered by changes of the sub-key of peripheral devices, the thread can determine the access status of peripheral devices according to the read sub-key and sub-key value of peripheral devices. The invention can be used in all computers with peripheral devices. The invention can accurately and easily check the access status of peripheral devices in time.

Description

technical field [0001] The invention relates to peripheral equipment monitoring technology, in particular to a method for detecting the connection status of computer peripheral equipment. Background technique [0002] Along with popularizing day by day of computer, computer peripheral equipment is also more and more contacted by people. Mobile hard disks, modems, USB flash drives, etc. are commonly used computer peripherals. The interface between the peripheral device and the computer is also very flexible, commonly used PCMCIA (Personal Computer Memory Card International Association) interface, USB interface, and expansion card (Express Card) interface. Compared with the PCMCIA interface, the Express Card interface has many advantages such as smaller size, faster transmission speed, lower power consumption, and more suitable for mobile systems. The application of the USB interface is even more extensive. At present, almost all notebooks and desktops are equipped with USB ...
