Hi,

https://www.cypress.com/documentation/development-kitsboards/cy4500-ez-pd-protocol-analyzer

Please install "Download CY4500 EZ-PD Protocol Analyzer EXE" from the above mentioned link. Installing this will automatically install the drivers necessary. If you still face issue you can manually reinstall it from the path i mentioned before.

Hi,

This occurs if a proper driver is not installed. Can you please try installing drivers from

C:\Program Files (x86)\Cypress\CY4500 EZ-PD Protocol Analyzer\1.0\EZ-PD Analyzer Utility

Also make sure proper driver is bound to the hardware in Device Manager

Ok thanks it's working now. I assumed "CY4500 EZ-PD Protocol Analyzer EXE"" was an old version since it hasn't been updated since 2016.

What's the difference between this and the "Utility"?

Hi

CY4500 EZ-PD Protocol Analyzer EXE installs drivers related to CY4500 kit. It also includes earlier version of EZ-PD Analyzer Utility( This utility can only decode PD2.0 packets).
