Research of the VxWorks-based USB Device Driver

YU Guo-qing

Abstract

VxWorks operating system with high reliability and excellent real-time is widely used in the field of embedded systems. In the paper,first the VxWorks operating system and USB2.0 protocol are analysed. Second the USB device drivers based on the ZX2930 EVB2.0 board have been studied. Finally the VxWorks-based USB device drivers are realized and the communication between the Personal Computer and the board EVB2.0 is successfully established. The experimental results show that the driver is stable and reliable.
