    How to protect  D+/D- data line in self-powered design

      I am working at small device maker.


      Where we are using the CY68013 to product .


      Two devices that were shipped recently has been returned in failure.


      I have received reports that D+/D- line is a short circuit. (shorted internally, not by board solder)




      What is the cause of a short circuit?


      Would there a way to protect on the circuit?




      for past few years, problems did not occurred.
