    modify cyusb3.inf fail

    dach_3214351

      I followed CyUSB3.pdf to add my own VID/PID pair to CyUSB3.inf file.

         

      I did the following, none of them work.  No changes to CyUSB3.sys and CyUSB3.cat

         

      1. Add my VID/PID to the .inf and change the strings. Remove all build in PID/VID and the strings, Keep the file name as CyUSB3.inf.

          But it never get work. The windows10 (64bits) always shows

         

      2. Only add my VID/PID and strings, without changing any original data in cyusb3.inf. it can install successfully.

       

      note: I have disable my computer Digital Signature.

         

      Can tell me the difference is there?

       

      Thank you.
