UDP
UDP: Bad Data in the First IN Data Stage
All or part of the data of the first IN data Stage are not transmitted.It may then be a Zero Length
Packet. The CRC is correct. So the HOST may only see that the size of the received data does
not match the requested length. But even if performed again, the control transfer will probably
fail.
These Control transfers are mainly used at device configuration. After clearing RXSETUP, the
software needs to compute the setup transaction request before writing data into the FIFO if
needed. This time is generally greater than the minimum safe delay required above. If not, a
software wait loop after RXSETUP clear may be added at minimum cost.
