Viewport Gets HMD Control Not Working with Vive

When using the Viewport Gets HMD Control option in the Editor Preferences, the Vive does not seem to be able to control the viewport camera, which is what would be expected.

1. Open the editor (ensure that the Vive is hooked up and Steam VR is running)
2. Go to Edit->Editor Preferences->Play and check Viewport Gets HMD Control
3. Attempt to move the Vive headset around to move the viewport

Result: The viewport does not move with the rotation of the Vive

Expected: The viewport camera would follow the Vive
