• If the packet length is odd, the upper byte of the last word in an IN endpoint buffer
is not transmitted to the host. When reading from an OUTendpoint buffer, the
upper byte of the last word must be ignored by the firmware. The packet length is
stored in the first two bytes of the endpoint buffer.
