Hi Matthias,

A zero length CSV is symptomatic of the file not being closed properly.
    Linus sent a hint that I should call fsync() after the write which
would be a better solution to the USB/zero length problem, but I have
not done that yet.

Ronald Teune generated a CSV yesterday of a charge cycle with a ~9v
charger supply so getting a charge sample from your set up is less
important now. I need to compare his results with mine (stock charger &
battery), but it looks good so far...

Thanks,
gvb
