Development and Implementation of Transmission of USB Device Driver Based on Linux Operating System

To develop a read-write control procedures which can support the USB communication between intelligent device and the host under Linux operating system, in order to meet the needs of the control and communicate, under the requirement of developping a USB device driver to establish the connections quickly and conveniently, meanwhile, the transmission between host and intelligent device must be correct and stable.In order to solve the above problems, this paper realizes the development method of USB driver based on CyAPI library under a Linux operating system.In the the development of read-write control procedures of intelligent devices, the USB driver is verified, by calling device driver directly realized the control of the USB device and data transmission, at the same time the information feedback of intelligent device can be received timely and correct, the device driver shows good stability.
