How to use custom VID/PID in CY7C65211A

[NXTY_Nishinaga]

Hello,

I would like to change the VID/PID from the default value to a custom value.

Referring to chapter 3.1 of the Cypress USB-Serial Configuration Utility 2.0 User Guide, I changed the VID/PID in the driver's INF file.

When I tried to manually install the driver in that state, error occurred and I could not install it.

(Error: File hash is missing in the specified catalog file)

How can I use CY7C65211A with custom VID/PID?

Or is there another way to work with custom VID/PID without changing the INF file?

Regards

Hi,

Please refer to the attached KBA for details on binding drivers for a custom VID/PID. https://community.infineon.com/t5/Knowledge-Base-Articles/Binding-Drivers-to-a-USB-Serial-Bridge-Con...

Let us know if the steps in the KBA are properly followed.

Best Regards,

Hello,

Thank you very much for your answer.

I believe that security measures in Windows 10 prevent us from using the edited INF file, but can we install it using the method you gave us?

As mentioned earlier, an error occurred during installation.

Hello,

I received the above response, but it does not appear to be the answer to my question.

I think it is an answer to another question.

Could you please check?

Thank you very much for your answer.

In conclusion, would it be sufficient to simply process the following?

It says to contact technical support, should I contact your company to request this?

After creating an account in the Windows Hardware Dashboard, kindly reach out to Technical Support and provide the following details:

The modified INF file with custom VID/PID for verification.
The publisher display name.
The OS for which they want the driver resell? Also mention whether it is needed for x64 OS architecture or x86 OS architecture or both?
The driver version they want us to resell.
The silicon chip they are using- FX3 or FX2LP or USB-Serial.
