* WARNING! TinyUSB can block output Endpoint for several RX callbacks, after will do additional flush
* after the each trasfer. That can leads to the situation when you requested a flush, but it will fail until

* SO USING OF THE FLUSH WITH TIMEOUTS IN CALLBACKS IS NOT RECOMENDED - YOU CAN GET A LOCK FOR THE TIMEOUT
