Hi Lee,

I had trouble parsing the previous message, the formatting was a bit 
challenging.

If you are sending discontinous data (bursts of samples as opposed to
continuous streaming) and if the end of a burst does not come out to a
multiple of 512 bytes (128 complex samples), then yes, there could be
data buffered and not yet sent.


I expect that with the introduction of "in band signaling" on the
data path of the USB, this requirement will go away.  However, this is
at least a couple of months out.
