If the driver sequence number coincidentally equals the previous command response sequence number, the driver may proceed with fetching the entire buffer before the OCC has processed the current command. To be sure the correct response is obtained, check the command type and also retry if any of the response parameters have changed when the rest of the buffer is fetched. Also initialize the driver with a random sequence number in order to reduce the chances of this happening.
