    driver of cy7c6813a

              I made a board which has CPLD and CY7C6813A when I connect it to pc sometimes pc couldn't recognize it .   
      I downloaded the Cypress Suit USB 3.4.1 and I changed the cyusb.inf for my own vendor (it is = %VID_0547&PID_1002.DeviceDesc%=CyUsb, USB\VID_0547&PID_1002) but when I try to force pc to use this driver pc gives this message: the specified location does not contain information about your hardware. Cypress does not connect to any EEPROM in this situation.   
      I was wondering if somebody can help me.
