 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




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

This is not a problem with the project or the drivers . This must be an issue with the board . 


One way to verify that is to swap the chip in the original working board with the chip in the non working board and connect both to PC . If the original board enumerates fine which mean the chip is fine and the project is fine and it is  an issue with the new board that you have designed .


If the working board fails to enumerate with the newly swapped chip and the other board is working fine it mean an issue in the project or in the chip.

Not sure if you could use Zadig.exe to force driver update.




 Or drivers in Cypress USB SDK disk.                   http://www.cypress.com/?rID=57990
