Dear mswynghedauw,
thank you for this feedback. Their actually was a bug in the released driver (I modified what Chris initially proposed). Chris did not notice it because the start button on his device hides the bug...
I quickly fixed it with some students (through VNC cause we don't have modular EEG at the lab) but did not include it in the SVN yet. I will study your code and see which one is best to include in the official release. Thank you for your time,
Yann
