Development And Design Of USB

This paper presents a method of design for and realization of data transfer with high speed and reliability for coloi inkjet plotter by USB so that it can draw with high speed and precision.The first part of this paper deals with the core content of Universal Serial Bus 1.1 Specification in detail,and provides fundamental knowledge and way of design in USB development. The second part of this paper mainly analyzes the actual biggest bandwidth provided by USB Spec 1.1. The last part of this paper describes the implement of engineering in hardware,firmware and host program.The data transfer of USB used in this paper conquers some disadvantages,such as low speed,complex of connecting and so on,providing a new pattern interface for the data transfer of plotter .
