Abstract
A method for modifying a USB device driver matching string includes: when a plug-and-play manager sends a request for querying device information to a physical device object, capturing, by a filter driver, the request for querying device information, and sending the request to an enumeration driver; receiving, by the filter driver, device information that is returned, according to the request for querying device information, by the enumeration driver, and forming, according to the returned device information and compatibility information of the device, a device driver matching string; and sending the device driver matching string to the plug-and-play manager.
