Pen Tablet(WH1409 V2) doesn't connect with my computer

The tablet doesn't connect with my computer neither wireless and neither with USB-cable. However it's quite odd that the tablet reacts when the pen is near the surface of the tablet also the according light signals do still work. Since the driver updated it didn't connected anymore and started to behave like this. Also the app or Programm still shows me that the device isn't connected.

What am I supposed to do. I tried literally everything from uninstalling the driver and installing the previous driver to shut my computer down; I even tried to connect it with my other computer but it still has the same issue...

I'm extremely frustrated...
