Check for running SteamVR

[A Wundlechner]

Thank you for your reply.

it also opens steamvr when I check for controllers by this command: steamvr.getControllerList()[index]

But it doesn't matter for me anymore, beause in the meantime I already found a solution for my problem. I installed the psutil library. I search with it for the running process "vrmonitor.exe". If I find the process, then steamvr is running.
