The Rift doesn’t like having things taken away from it, especially USB resources….
Not… one … bit.
As a small dev, we have a bunch of 1Tb USB 3 drives for backup… I know… you are going to laugh at me.
Anyway, one of our drives failed, so we plugged in an external USB3 drive to one of our dev machines and… VOILA… utter corruption.
When we re-booted, Oculus thought I had bought a new device. It forced us to go though the WHOLE setup again!
… I laughed …
After smashing many objects, we got our stuff back. But beware everyone, if you have a Rift, make sure that is the ONLY thing using USB.
