Coming from the embedded world and not knowing much about this, I tend
to wait until the above issue is clear, meaning when and how this driver
is safe to be used. I hope you don't mind. Keeping your code up to date
and sharing it is much appreciated, though! As well as Guenter's comments.

Thanks!
