Steps to launch VirtualCast from Steam
SteamVR can be launched from the icon in the upper right corner of the Steam app.
When SteamVR launches successfully,
green icons of an HMD, controllers and base-stations will be shown as the figure above.
(Oculus and Windows MR have different icons for each system)
In case of errors
It might be the case that USB cables, HMD cables or power cables are not connected properly.
