If you are interested in changing the Cypress driver to reflect your own identity through custom USB Vendor IDs (VID), Product IDs (PID), product names, company names and performance options, you can do this by editing one or both of the driver INF files. Once an INF file is edited, the original digital signature is no longer valid. Cypress can re-sell the existing driver certification to customers. Customers will have to submit the modified driver package to get Microsoft certification.
I have the same problem with the certification for Windows 7/10.
I have EZ USB FX2 with VID/PID 0547/1002 which is not included in the INF file of the FX3 drivers.
I create a Test catalog and change the PC to load in TESTSIGNING ON (to be able to check the drivers of Windows 10).
In this mode I can use the FX3 drivers and communicate with the FX2 device as necessary.
Now I need a Microsoft certification in order to use the drivers in a release mode.
As I understand from you, it is possible to do that by submitting the modified driver package to Cypress.
Can you tell me how to proceed? How to submit the new package and how long it takes to receive the new Certified package?
