Sooo, when I launch Oculus Home, I get a feed, tho I sometimes need to restart the DK2 a few times to get it, after I got it, I go to the settings, devices, configure Rift, run full setup, then I go to the configure screen, click next, then I see this: https://gyazo.com/133ac2653b9db9e1f530d20c55a0477a and it never sees the HDMI or USB from the DK2, despite the fact that I can look in the rift, and see the text "Rift isn't ready for you just yet", and even play Project Cars from SteamVR, which runs perfectly, except the fact that my GTX660 can barely hold 45FPS (Asynchronous Time-Warp helps alot here).
I have the exact same issue with my DK2 during setup. I have an Asus ROG G752VT with a GTX 970m. All the usb ports are usb 3.0 and with updated drivers. I hope someone can shed some light as to why this is happening.
I'd try different USB ports (both USB 3.0 and 2.0) and using a different video port (for example, with a DisplayPort-to-HDMI adapter). Also, laptop mobile graphics chips are not supported.
