Abstract

The invention is suitable for the technical field of data transmission and provides a method and a system for recognizing USB equipment. The method provided by the invention comprises the following steps of: when detecting the USB equipment to be plugged in, reading information of the plugged USB equipment; comparing the read information of the USB equipment with information of a protocol driver of the Windows operating system to recognize the USB equipment; when the read information of the USB equipment is matched with the information of the protocol driver of the Windows operating system, judging the plugged USB equipment to be the plug and play equipment to realize the read-write of the USB data. The technical scheme of the embodiment provided by the invention realizes the transmission of any data between the USB equipment and the PC (Personal Computer) machine without carrying out a development of the driver; the method and the system provided by the invention are convenient for users to use and really realize the plug and play function of the USB equipment.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to an identification method and system of a USB device. Background technique [0002] At present, there are many USB interface products on the market that need to install drivers on the Windows operating system before they can be used normally, and the suppliers of each product need to write USB underlying drivers of different versions of the Windows operating system for these USB interface devices. , Windows platforms including windows2000 / xp, VISTA, Window7, etc., in order to meet the needs of the market in terms of PC architecture, drivers for 32-bit machines and 64-bit machines must also be designed. Regarding the design of the windows driver, the product development cycle is long, which is a serious obstacle to whether a product can be launched on the market in time. On the other hand, in order to standardize the drivers, Microsoft strictly restricts the ...
