    USB device not detected

    dee.kay
              I am trying to run a USB sample program on CY8C24894 device. I made a new board and the device on the board is prorgammed fine wiht PSoC miniprorgammer. However USB is not detected by the PC. I created a new project absed on the AN50989   
         
      The same program created for CY8C24794 on the development board does works fine   
         
      I duplicated the following for my device from AN50989:   
      1] Sample C program   
      2] POrt connections as in GUI setup   
      3] USB setup for HID device class   
         
      I downloaded another sample application for this device . This time PC detects the USB and installs device driver. Howvever, when I am trying to access the device through GUID interface, I get VID=0 and PID=0.   
         
      I donot know if I am missing something.   
         
      I would apprecite your help.   
         
      Thanks in advance.
