USB EZ-PD Type-C

I'm trying to use the EZ-PD Configuration Utility to view and change the settings on the CY4531 CCG3 EVK.  I installed the software then connected a USB cable between the CY4531 USB micro B port and my PC.  I also have the provided power adapter connected to the CY4531.  I'm running Win 10.

When the EVK enumerates, the only new entries I can find the Device Manager are two "USB Serial Port" entries in the Ports section.  One is COM18 and one is COM19.  The VID and PID are 0x04B4 and 0x0005.  Both devices show that they are working and there are no Unknown devices shown.

But in the EZ-PD Configuration Manager shows no devices connected:

Hello Tony,

I understand that you are not able to see the EVK in the Configuration Utility.

Is this the first time you are using this EVK or has the firmware been changed before?
Has the configuration of the serial controller been changed?
The controller CY7C65215-32LTXI must be set in I2C vendor mode.
Please refer to the following thread for further information on this:
https://community.cypress.com/t5/USB-EZ-PD-Type-C/problem-configuration-utility-can-not-detect-devic...

Normally, these would be the devices added to device manager:

Do you see any new devices under Universal Seria Bus controllers?

When you do "File"-> "Read from device", does CCG3 appear as in the picture?

Best regards,
