Astra SDK doesn't deliver depthframe

I started to get depthframes with OpenNI-interface (Astra S) and everything works well.

Now i wanted to get the depthframes as shown in the astra sdk tutorial. My problem is similar to this topic: Why does get_latest_frame() deliver no frame?

Neither the procedure with “get_latest_frame()” nor the procedure with the FrameListener are working. In the first case my program stops at “get_latest_frame()” and waits the whole time for the frame. In the second case the listener waits the whole time for a frame but there isn’t one.

I’ve changed the usb-port - still the same problem.
I’m wondering because the samples in the SDK (they use the same functions) are working well.

Are there any experiences with these issues?

Thank you!
Best regards,
