The Index thread (please keep to subject)

@RuneSR2, how are you managing your Index/Rift cv1 on your PC.  I have currently uninstalled my cv1 so I can fully test out my new Cosmos.  I did reinstall Oculus software to try out Revive but I did not get very good results because of the poor Cosmos controller compatibility so I would like to reinstall my cv1.  Thanks mate.

Reading so much about problems connecting Rift-S I've been a bit worried about deactivating the CV1, but so far it hasn't been a problem. Seems like you more or less can remove at least the CV1 usb connection much like you add or remove an USB flashdrive, lol. So insert the CV1 usb and it'll show connected in the Oculus Desktop app - and disconnected when you remove it. 

I have a special usb-c 3.1 Gen2 "VR Ready" port on my motherboard - maybe most of us do - so I bought this solution:


Here I can turn off an usb port when I don't want it active (much easier than having to find an unplug the cable at the back of the rig). My CV1 is now plugged in the usb 3 hub and I turn it off when I use the Index. Index is always connected and never deactivated, but is only active when SteamVR has started. 
One problem may be to use CV1 in SteamVR, because then you'd have two active HMDs competing, so I never start SteamVR when CV1 is active. I only use CV1 for games bought in the Oculus Store. And I only use Index for games bought on Steam. This way the HMDs are completely separated - CV1 for native Oculus, Index for SteamVR. This was my plan already when buying Index, because I never was a great fan of how SteamVR worked when using CV1. With Index I got native driver support in Steam games. And you can revive Oculus games inside SteamVR if needed. 
To use CV1 in SteamVR, then Cosmos/Index should first be disconnected - but I have not tried that since some had problems getting Index working correctly and I'm not going to risk creating problems. This isn't a problem, because I can't think of any SteamVR game where I'd want to use CV1 instead of Index. 
Having Index connected when starting Oculus Home is a not problem, the Oculus software doesn't recognize the Index at all - and the Index doesn't react to the Oculus desktop app when SteamVR is running. 

In short - activate the CV1 usb when you want to use Oculus software - leave Cosmos constantly connected and only use Cosmos for SteamVR. 

Using my GTX 1080, Index and my plasma TV are connected to display ports, while CV1 is connected to HDMI - I never unplug these cables. I never unplug or deactivate the 3 CV1 external sensors. 

That sounds like a good plan mate!  Many thanks for all that.  Cheers.

You're more than welcome, let me know if something doesn't work. BTW, been spending most of my time in CV1 the last week because of Asgard's Wrath - I think it adds to our quality of life having more HMD options, lol. Also like having a VR back-up plan if one HMD should fail ;) Or just having the ability to enjoy the best of both worlds without needing two rigs. 
After having used Index for several months, at first it was really hard adapting to the CV1 in Asgard's Wrath - now I've gotten used to CV1 again, and I love the feeling of nostalgia using CV1 - and Oculus Home starts a lot quicker than SteamVR.

Do you have a link or model/brand of that Hub?

I got this one - I think you can find a lot of similar products on eBay or Amazon:

You're welcone - btw, if you just need a switch for CV1, you may of course not need a type-c hub, but can just get a normal type-a hub. If you plan to connect more devices than CV1 to the hub, then - maybe - type-c can have advantages. Usb 3.0 type-a can provide up to 4.5 watts (900mA x 5V), so some USB 3.0 type-a hubs include cables for external power, which I'd rather avoid.
The great thing about usb-c Gen2 is that it's capable of delivering a massive 100 watts of power (5A, 20V) and a massive 10 Gbit/s (type-a is 50% of that) - so using such "VR Ready" type-c Gen2 ports may provide more than enough power and bandwidth even if connecting several usb 3.0 devices to the hub.

I used type-c for the hub because I only have 2 VR-Ready ports on my motherboard, one type-a and one type-c, and Index uses type-a (for what it's worth I like to use the MSI certified VR-Ready ports for the HMDs). The rest of my usb3-a-ports on the back of my rig are taken by the CV1 sensors. 

Thanks, main reason I might pick one up is just for convenience sake in being able to turn the USB off easily.
