Changing Serial CDC name

[geraldjust]

Hi there , i was wondering if anyone has a way to change the "name" of the USB_PRODUCT_STRING from the built in ones to a custom string.

Acording to https://github.com/stm32duino/Arduino_Core_STM32/blob/master/cores/arduino/stm32/usb/usbd_desc.c
line #67 looks like if i define it it will change it but i have not been able to do that. I can easily change the VID and PID via boards.txt by adding build.vid=0x239A as a example.
But was wondering if there's anything similar like that compiler flag to set USB_PRODUCT_STRING to a custom string.

Thanks!

Hi @geraldjust
you can try to use the build_opt.h: https://github.com/stm32duino/wiki/wiki/Customize-build-options-using-build_opt.h

-DUSB_PRODUCT_STRING="custom USB"
