[Abstract]:USB interface has been widely used because of its support for hot plug and play and plug and play. More and more host devices begin to use USB interface for data transmission. However, how to transfer data without changing the existing application software, Porting devices to USB interfaces has become a hot topic. Based on the abstract control model of USB communication device class, this paper studies the specification of communication device class and the principle of realizing virtual device, and designs and implements the driver of virtual serial port based on communication device class. The structure and implementation scheme of the virtual serial port driver based on the communication device class are studied and designed in this paper. The program consists of two parts: communication command conversion and data transmission. The communication command conversion accords with the standard of abstract control model in the class of communication equipment. In the part of data transmission, the implementation technology of the existing virtual serial port is improved. The main work of this paper is as follows: the request and transmission mode of USB protocol is studied, the scheme of communication device class virtualization device is analyzed, and a virtual serial port implementation scheme which accords with the abstract control model in communication device class is presented. This scheme provides a template for developing virtual devices based on communication devices, explains in detail many problems in the design, and improves the processing flow of data in the virtual serial driver. The improved data processing flow is applied to the implementation of the virtual serial port, and a stable and high-speed virtual serial port based on the class of communication equipment is generated. Finally, the data transceiver module of virtual serial port is tested and the expected target is achieved.
