              I have developed a board in which I have used EZ-USB FX2LP dveice CY7C68013A for data transfer from HOST PC to FPGA. I am facing problem in device detection on the host pc (Windows XP). As I connect the USB cable between CPU and the board on the computer there is no notification pop up for deveice detection. When I look into the device manager window the device pannel is getting refreshed continuously. I have checked all the voltage leves required on critical pins thoroughly as per the guideline provided in documents. Please assist in this regard.

          您好：

             

             我用68013A-100这个芯片，想把端口配置成 ISO 传输模式，可是，配置寄存器EPXCFG之后，用你们的开发工具CONTROL PANNAL 中的GET PIPES，

             

          Pipe:  0   Type: BLK Endpoint:  2 OUT  MaxPktSize: 0x200
          Pipe:  1   Type: BLK Endpoint:  6 IN   MaxPktSize: 0x200

             

          没有找到想要的ISO传输模式的端口，请问这是怎么回事？如何配置，才能正常工作。

             

          谢谢您的浏览，期待您的回复。
