The documentation for the USB ROM APIs does not go in much detail on the implementation of custom classes. There in an FAQ How to implement custom class device? but it is empty. Other parts of the documentation make brief mention of the general steps without much detail. The usb_csc.c example does override the data endpoint handlers with USBD_API->core->RegisterEpHandler() but doesn't override the control ep0 endpoint handler with USBD_API->core->RegisterClassHandler(). Is there a working example of a custom class with the USBD ROM API that overrides the ep0 handler?

Thanks.
