I've two boards with same circuit based on CY7C68014A. Though one of the boards is working fine, other board is not working correctly and windows reports code 43 error during driver installation.

   

I noticed that non-working board has +3.3V on D+ line. While I'm able to debug the board through serial port, USB connection is not working. Please advise.

        Please check the USB connector soldered on the board. Improper soldering might cause an issue
