Modifying USB descriptor values in CubeMX

nagahimanshu7 · ‎2025-01-06

Hi,

I am working on USB Device Middleware on STM32F469NI using STM32CubeMX. For our use case we have to modify the PRODUCT_STRING descriptor value (default is "STM32 Virtual ComPort"). Is it recommended to perform this, or are there any STM standards for these values?

Thanks,

Himanshu

Hi @nagahimanshu7

Of course, you can change PRODUCT_STRING descriptor. Only PID and VID are specific identifiers for USB devices, you can request PID in OLS ticket. Are you sure about your VID 0x0456?

Hi @FBL,

Thanks for the clarification.

Kindly ignore the modification to that VID and PID in the screenshot as it is temporarily adjusted for our early-stage development with one of our GUIs. Sure, we will raise an OLS ticket if that modification becomes a long-term requirement.

Thanks,

Himanshu
