Abstract

The invention discloses a method for testing USB (Universal Serial Bus) equipment of an electronic device, which is used for testing whether the electronic device provided with a USB interface is in good connection with the USB equipment or not. The method comprises the following steps of: providing a storage unit, wherein a product identification code of the USB equipment should be connected to the USB interface is stored in the storage unit; checking the product identification code of the USB equipment connected to the USB interface by a test module; and comparing the product identification code of the USB equipment with a product identification code in the storage unit, if same, indicating that the electronic device is in good connection with the corresponding USB equipment, and if not same, indicating that the electronic device is not in good connection with the corresponding USB equipment. The invention also provides a system for testing the USB equipment of a computer.

Description

technical field [0001] The invention relates to a testing method and system, in particular to a method and system for testing USB equipment of an electronic device. Background technique [0002] With the rapid development of electronic technology, there are more and more peripheral devices of various electronic devices, such as computers, and various peripheral devices such as keyboards, mice, modems, printers, scanners, cameras, etc. need to be connected to the host computer. In order to realize various functions, in order to allow these devices to be conveniently connected with electronic devices, USB interfaces are widely used. [0003] According to the provisions of the USB specification, all USB devices have a vendor identification code (VID) and a product identification code (PID), and electronic devices of electronic devices distinguish different devices through different vendor identification codes and product identification codes. Both the supplier identification c...
