Okay, my Z-Wave stick is toast. I don’t know if it was your binding scanning the USB Ports or something different.
So as a Warning until this can be confirmed: Don’t scan with this binding when you have your Z-Wave stick plugged in 
Maybe you should make adding the JeeLink as the Z-Wave binding does it - you can see it in
(Interessting Pictures are 17 and 18).
Thank you anyway for this great Binding, I’m off to get a new Stick. No worries about the old one
