Xi Chen · Jisuanji fangzhen · 2003
This paper firstly gives some research on USB interface system applied in communication. Then a complete USB communication interface system is propose d. The system includes the electrical circuit, the firmware and the Windows devi ce driver. The operating principles and applied circuits of the USB interface c hip USBN9602 is emphatically analyzed in the paper. It also introduces the princ iple of USB Windows device driver. Finally the USB interface is realized by comp uter programming .The experiment suggests that data transport ratio of the syste m is about 500Kbps.
