Ok, looks like I was a bit hasty.  Looking at the data again there does
appear to be a length field in the returned data however.

1) It's 19 bytes rather than 20.  This is a internel data format length
though.  The USB data returned is still 29 bytes long.
2) You still need to apply to four byte shift for it to be in the "right"
place.
