We are planning to use the CY7C65213 USB chip in some of our hardware and program our own USB VID/PID. I have seen on this forum that you can simply modify the cypress .inf file to add the custom VID/PID and then manually update the driver. However, doing so invalidates the Windows device signing and prompts the user with a security message. We need to be able to install the updated driver directly from our installer, without user prompt and have it recognized as a signed Windows driver.
What is the process to get an officially signed Windows (and MacOS Catalina and older and Big Sur and newer) driver package that uses VID/PID's? Can Cypress handle this for us, or do we need to build and submit our own custom driver? If the latter, what is that process?
Solved! Go to Solution.

Hi,
Please refer to Driver resell section present in the attached file.
Please modify the driver package to include custom VID/PID. Make sure that the driver doesn't carry any Cypress specific VID and PID.
Please give us the following information to proceed with driver resell process.
- The modified inf file with custom VID/PID.
- Publisher display name of Microsoft Windows Hardware Dashboard account.
- OS and architecture to which driver should support.
- Driver version.
- Silicon chip they are using- FX3 or FX2LP or USB-Serial.
