When sending data where size is larger than wMaxPacketSize, it will automatically send multiple USB packets where last packet size = {remaining size}. Every {wMaxPacketSize}-bytes is a different packet.

When sending data where size is larger than wMaxPacketSize, it will automatically send multiple USB packets where last packet size = {remaining size}. Every {wMaxPacketSize}-bytes is a different packet. This only occurs in some cases. When '''size''' is ~0x1000000(exact size unknown), Switch-side silently hangs, while host-side will timeout(no traffic on USB bus indicating failure).

For receiving data, if size is less than {actual received USB packet size} the rest of the packet will be discarded. Later PostBufferAsync cmd(s) will only return data from new packets, not the remainder of the earlier packet(s).
