Good day The application I got here needs high speed packets to be transmitted to an Interrupt endpoint with more than one transmission per frame, the packets are in a certain order. In the case of dropping a packet due to an error or sth, it is reasonable to retransmit the same packet before sending the next one, is this the case in USB2.0? and does it retransmit within the same frame?
