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.
