I followed CyUSB3.pdf to add my own VID/PID pair to CyUSB3.inf file.

   

I did the following, none of them work.  No changes to CyUSB3.sys and CyUSB3.cat

   

1. Add my VID/PID to the .inf and change the strings. Remove all build in PID/VID and the strings, Keep the file name as CyUSB3.inf.

    But it never get work. The windows10 (64bits) always shows

2. Only add my VID/PID and strings, without changing any original data in cyusb3.inf. it can install successfully.

note: I have disable my computer Digital Signature.

   

Can tell me the difference is there?

Thank you.

Hello,

- Please ensure that the files CyUSB3.SYS, CyUSB3.CAT and the WdfCoInstaller01011.DLL (For driver versions below 1.2.3.20)files are present along with the CyUSB3.INF file in the driver package folder.

- Also, it looks like you are using an older version of the driver. Please use the latest version 1.2.3.20 from the FX3 SDK.

I have attached the modified INF file along with the complete driver package which is working fine at my end. Please test using the same too.

Best regards,

Srinath S

Hello,

- With the same steps you have mentioned in (1), I am able to install the driver successfully. I removed the existing VID/PID and the strings from the INF file and added a custom VID/PID combination along with its string. I put the OS into Test mode and I am able to install this driver successfully. Please let me know if you are disabling the signature checking in the BIOS or are you driving the OS into Test mode.

- Please share the INF file for me to test at my end, if possible.

Best regards,
Srinath S
