* \retval non-zero Actual number of block that application can receive and must be less than or equal to \a \b block_count.
* \retval zero Indicate error in retrieving data from application. Tinyusb device stack will \b STALL the corresponding

* \note Although this callback is called by tinyusb device task (non-isr context), however as all the classes share
* the same task (to save resource), any delay in this callback will cause delay in reponse on other classes.
