+/// writing USB packets with no intermediate buffers, but it will not act like a stream-like port.
+/// The following constraints must be followed if you use this class directly:
+///
+/// - `read_packet` must be called with a buffer large enough to hold `max_packet_size` bytes.
+/// - `write_packet` must not be called with a buffer larger than `max_packet_size` bytes.
+/// - If you write a packet that is exactly `max_packet_size` bytes long, it won't be processed by the
+///   host operating system until a subsequent shorter packet is sent. A zero-length packet (ZLP)
+///   can be sent if there is no other data to send. This is because USB bulk transactions must be
+///   terminated with a short packet, even if the bulk endpoint is used for stream-like data.
