Oculus DK2 not working with Unreal 4.13

Hi , I’m working for my final year project which will be in VR and I’m using Unreal to create the game I want.

But it seems that Oculus DK2 is totally unresponsive in VR Preview and I couldn’t find any fix to make it work. I have everything checked in VR Plugins , outside of Unreal , the DK2 works with no problems at all.

Is there any fix for this?

You need to update firmware i think -
