NOT USED THIS QUARTER
If the Vive VR is not working with the headset
Start Steam 
First time use, Steam will ask you to login, you may set up an account or use the department's account: login dmaucla password UCLAdma!
This login seems to hang. It should work OK if you try restarting your Unity project. Worse case reboot the computer.
Make sure the headset and controllers are connected
Try wiggling the Headset.
Try pressing both the round buttons on the controllers together.
Make sure the hand held controllers are charged.
Steam Status Utility will look like this if it is ready.
Reset Steam if you don't see all the icons

Select Devices->Reboot Vive headset
There is also a menu to Run Room Setup, this should be done already
