USB Superspeed Peripherals

Hi. Our company use CYUSB3014 for our product.

We purchased VID from USB-IF since the VID/PID from cypress can be used just for development (NOT for release).

The target OS is Windows 10 (10.0 build 19041)

To Add our VID/PID to driver, CyUSB.pdf which is document included on SDK said we should modify cyusb3.inf

and get catalog file. But, we have a problem while generating catalog file.

 

Here's what I did.

1. modify cyusb3.inf  as below(located at C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\driver\bin\Win10\x64)

 [Device.NTx86]

 %VID_XXXX&PID_YYYY.DeviceDesc%=CyUsb3, USB\VID_XXXX&PID_YYYY ; add our VID/PID , (XXXX,YYYY : vid/pid from our company)

[Device.NTamd64]

%VID_XXXX&PID_YYYY.DeviceDesc%=CyUsb3, USB\VID_XXXX&PID_YYYY 

[Strings]

VID_XXXX&PID_YYYY.DeviceDesc="OUR COMPANY PRODUCT NAME"

CYUSB3.GUID="{generated GUID key from Microsoft's Guidgen tool}"

 

2. Run the infverif.exe (latest version of ChkINF tool) to verify the modified INF file is error free

--> as a result, the Log showed INF file is not valid.

3. Run Inf2Cat.exe to re-generate the CAT file.

--> as a result, Unable to create CAT file.

I cannot proceed more because of the errors.

Is there a way I can fix these problem?

Hi. Mallika

To give you the modified inf file, I moved the files to the Desktop path and tried again.

And then I succeeded to get the Catalog file on this time.

Thankss Maillika

Maybe, the location of the inf file was the problem.

 

But, I still get a Error Message when I try with the infverif.exe.

Will this be a problem?

I attached my modified.inf file and cyusb3.sys file.

Hello,

Please recheck and ensure the inf file does not contain any Cypress VID/PID other than bootloader VID/PID of the device.

I can see some Cypress VID/PIDs in your inf file. Please modify.
