    I don't know whether this is a bug or just wrong usage of the tool wizard.

    This is how i fixed it without modifying middleware components:

    Add ./RTE/USB to the include path (or wherever your custom class header files are located)
    Add #include "USBD_Config_CustomClass_0.h" to USBD_Config_0.c

    Best Regards,
