    USBUART driver not installing this time around

    helmut.forren

       I have a custom board with PSoC5 using USBUART.  In the past, I got this board version working and enumerating just fine.  Today, I pulled out a second board made at the same time as the first one.  I programmed the PSoC5.  I inserted the USB plug into my PC, and things aren't behaving.

         

       

         

      Specifically, in Device Manager I see the board identified as "Unknown Device".  I tried to update the driver, providing my ...Generated_Source\PSoC5 folder name.  Windows told me the driver was up-to-date.  Nevertheless, it's not installed properly.  The driver is from Microsoft, date 6/21/2006, version 6.1.7601.18328.

         

       

         

      Meanwhile, I still have the original board that works.  I plug its USB cable into my PC and it comes up just fine as COM9 in the Device Manager.  It says it's using a driver from Cypress, date 3/5/2007, version 2.0.0.0.

         

       

         

      What step did I forget?  How do I force windows to use the Cypress driver?  

         

       

         

      I'm using Win7 SP1, 64-bit, 32GB ram, Intel I7-2600 3.4GHz
