Hi,
tricky case indeed.
I agree with Jenny that Tobii hasn’t done any changes, which would have caused that (at least we’re not aware of any).
At the same time we don’t test together with Kinect V2 as Microsoft is anyways quite clear that the USB 3.0 controller should be dedicated to the Kinect. Which means, that Micrsoft knows that they need so much bandwidth that they can’t handle 2 devices using the same USB 3.0 controller.
Have a look here: https://dev.windows.com/en-us/kinect/hardware-setup
