How can you play Minecraft on the Oculus Quest?

I recently got an Oculus Quest and I want to play on this Minecraft in VR (Vivecraft). But SteamVR says it didn't find a device. A man in a YouTube tutorial said you only had to restart the computer, I did it and now it always says: "Please make sure that your video cables are firmly connected"

By the way, I use Virtual Desktop because I don't have USB 3.0 …

Maybe someone can help me there!

Buy a USB3.0 or better a USB3.1 cable. Is really better and the Oculus can then be supported directly.
