Hi Daniel,

Thanks for the response. I was experiencing timeouts that were traced
back to dma incompletions. Changing the script at the time fixed that
issue. Now, given your response I went back and checked this again and
verified that script 2 does work for me now. I did change firmware to
the latest v4.4 from something quite old so now I'm suspecting I had
bad firmware loaded up. Does that sound plausible? In any case, I can
confirm this is not needed.
