Abstract: With the increasing development of the communication technology, the universal serial bus (USB) as a new interface technology that makes the connection of PCs with peripheral

equipments very simple has been extensively adopted. The feature of USB2.0 is introduced firstly, and then the overall plan for designing the control system by using CY7C68013A is presented. The function of the system firmware and the design of drive program are discussed in detail. The key issues which should be taken more attention during the system design are proposed. The control

system firmware is programmed with C language. The control interface on PC is developed under the

ent. The experiment indicates that the whole system runs

perfectly well.
