I have now the oculus rift cv1 and I want to upgrade to the oculus quest because of the new link feature, my question is which cable should I use for it because I don’t have usb type c in my pc but I do have usb 3 so can I use a usb type c to usb 3 or I can’t use it at all and I don’t want the rift s because I love OLED screen

    First, I just would like to make sure you are aware that the Link functionality is not yet enabled. It was announced that it will be released in beta form in November. Second, the USB 3 standard uses different kinds of connectors. Desktop computers usually have type A, which is the rectangular one and usually is blue in colour. Type C is the small rounded rectangular one that phones and the Quest has. They are all USB 3, it's just different physical connector. This means that as long as your computer has USB 3 ports (which I assume it should since you have been using the Oculus CV1), regardless of if the connector is type A or C, you should be fine and Link should work.

    As for the cable, Oculus said their own cable would be the best for performance (it will use a fiber optic between the device and the computer) and that it will go up for sale "later this year". In the meantime you could use a regular USB 3 cable but you might get data transmission issues depending on quality and length (possibly manifesting as dropped frames, lag, pixelation or whatever Oculus decides to show you when the data is not being transferred fast enough). If you want to purchase a USB 3 cable then in your case you will likely need one that has type C on one end and type A on the other so you can plug it to your desktop.

    Cheers!

    They've said it should work with a USB 3.0 A to C cable.

    I expect that a USB A to C adapter should also work (although that hasn't been officially tested and confirmed), and would allow you to use the official Oculus Link cable plugged into a USB 3.0 A-type port on your computer

    Aren't native USB type-C to USB type-C cables actually a bit faster than USB 3.0 type-A to USB type-C conversion cables?

    I thought the whole point of a USB type-C cable (at both ends) was faster data & charging rates.

    Come November I'll be testing both out during the beta phase, and then possibly upgrade to the Oculus Link cable if the PC feature looks promising and performs well.

    USB C is just the connector type. The speed is defined by the protocol, which in this case is USB 3.0, because that's what the Quest is limited to. (They're not even maxing out USB 3.0, because the Quest's decoder can only handle 150 Mbps.)

    USB C is more commonly used in the newer USB 3.1 and USB PD specifications, which do allow for higher speed and more power, but that doesn't apply to Oculus Link.

    It depends on the cable. USB-C to USB-C can be USB 2.0, which is massively slower than a USB 3.0 A to C cable.
    The current Quest charging cable is an example of this, it can only handle USB 2.0 speeds even though it is USB-C on both ends.

    if I don’t have usb type c connection in my pc but I do have a usb 3 A , 
    So does a Usb type c to usb 3 A will work as good as my oculus rift cv1?

    Thanks for the clarification folks.

    That also explains why Oculus has stated that the included USB-C cable will not be suitable since it is only capable of supporting USB 2.0 data speeds.
    I'm hoping that the USB-C port with a bracket I've ordered for my mobo also comes in handy for the Link cable, as I have a USB-C connector on my Gigabyte Aorus Elite mobo which is currently sitting there unused.

    Luckily I have several different USB 3.0 type-A to USB-C cables on hand to test things out with using standard USB 3.0 ports during the beta phase.
    I'm hoping that my magnetic one works, as better safe than sorry with that fragile USB-C port on the Quest.

    For standard cables,I guess we'd better start 3D printing some cable-clips as a safety measure.

    USB 2.0 has a maximum 480 megabits per second (480 Mb/s), while the Quest's internal chip is limited to only 150 megabits per second (150 Mb/s).

    I'm curious about if Quest could someday have a direct connector to HDMI as Rift or there is any limitation that implies the use of USB cables. Anybody know what is the reason for this? A Quest that could be connected to a PC through HDMI I suppose wouldn't need the extra delay time compressing data that now Quest is going to require with Link.
  • nalex66nalex66 Posts: 5,516 Volunteer Moderator
    For the current Quest it's a limitation of the SoC they're using. I believe that later SnapDragon models may be able to take a direct video feed. On the other hand, their current course of development may be very useful for future innovation. They've got the latency pretty low, and it sounds like Carmack believes that it can be further improved. Having their own high-efficiency encoding/streaming process may pave the way for high quality wireless PCVR, and could eliminate the issues with trying to get direct GPU feed out of many laptops.

    That’s right, the charger cable is only USB 2.0, and won’t work for Oculus Link.

    My Mac is reporting 5Gbit connection to quest if iam using hq thunderbolt 3 cabling. Even 150mbit or 15mb/s woulnt be enough for a compressed stream for both displays in my opinion.

    Definitely, the charger cable barely even works with sidequest!

    There's 8 bits to a byte, so 150 megabits (Mb) is only 18.75 megabytes (MB). A 4K video, 3840x2160 @ 60 fps from Netflix is only 128 megabits per second (Mb/s). The Quest is 2880x1600...slightly under 3K @ 2880x1620 @ 72 fps. On top of that, the image gets reduced to the Rift-S's resolution of only 2560x1440. There's more than enough room.

    First I wanted to buy Quest as my first VR but now.. I cant decide. Honestly I don't think oculus link will be that good. Probably it wont let playing games with small details like simulators, latency sensitive games and games with high quality graphics due to low bandwidth and extra amount of PC power used for video encoding and transferring and not everyone have 2080ti to render game in high res and then encode it..
    So what’s the point of link?

    Streaming Steam VR games on Virtual Desktop over wifi works great for me, so USB 3 should be absolutely perfect!

    So i am thinking of buying the Oculus quest, but i am not completely understanding what the oculus link update does.
    Will you be able to stream from your pc to the headset or download the games to the headset?
     My computer also doesn't have a USB-C port, and i dont want to buy a whole new (expensive) graphics card only for 1 new port, but i have USB-A, will a cable from USB-C to USB-A work?

    Quest Link will make your PC think a Rift is plugged in. It will stream game video to the Quest for display, and send the Quest's tracking and controls back to the PC. So it effectively turns the Quest into a Rift (although using compressed video streaming instead of a direct video connection). The Quest itself isn't running the games, there's no downloading to it when using it as a Rift.
    A USB-A to USB-C cable should work, assuming it's USB 3 (not all of them are). But since it's not out yet, none of us can guarantee a certain kind of cable will work. Oculus have a bad track record with USB. :)

    Confirmed to be working. Look for it on Amazon. Can't post links yet.

    You can also use an active USB 3 extender. I have a Cable Matters one that is 16 feet long giving me 26 feet to play with. Also can be found on Amazon.

    With Oculus Link - will the Quest run on the internal battery or will the Quest receive the necessary power from the PC / USB cable?

    The Oculus Link cable has 3a power, which is the same as the Oculus power adapter. So should be able to power the Quest headset. 

    My Anker USB 3.0 cable also appears to be powering my Quest fine. The internal battery doesn't appear to be depleting. Just been playing for a couple of hours and battery is at 100% when I unplug the cable.

    I use an Anker PowerCore 10000 PD battery pack with my Quest, plugging the cable into the 3A PD port. The only time I have an issue of the Quest draining faster than the battery, is if the Quest has a 95% or less charge when stating up. For whatever reason, it works best when the Quest is fully charged, or 95% or higher, and if I power on the Quest before connecting the battery cable. As long as I do that, the Quest stays completely charged. But if it's 95% or less, or I power the Quest when it's already connected to the battery...the Quest drains faster than it charges. Also, powering on when it's connected to the battery requires you to hold the button in for more than 5 seconds until it actually chimes and boots. At first it seems like it's not going to boot, then it finally does. Very deceptive. :P

    Is this the Anker cable that Facebook was recommending? I'm planning on the 10ft cable, then connecting to the 15ft Monoprice active usb 3.0 cable Oculus recommended for the Rift CV1. Sebastian of MRTV confirmed a 1m cable connected to a 5m CableCreations active cable works fine, and the Rift CV1's cable's 4m, and that's longer than the 10ft Anker cable, so it should work flawlessly. Hopefully. I'm choosing the 10ft cable, as it'll give enough length for the cable to connect to the extension on the floor, and not have the weight of the connector and thicker cable of the extension running down my back. It won't be here until Sunday though. :(

    You know, I don't know if I am just missing it, but in everything Oculus themselves have said, I've always left confused as to exactly what Link does/means. Thank you, kojack. You finally answered the question I have that Oculus never made clear.

    They made it clear you can now use Link to play Rift games on the Quest. They made clear you need to do so by connecting the Quest to a VR ready PC with a specific kind of cable. But what I still didn't understand was do you then download the games to the Quest and are able to play the games via the Quest alone? Or does it at least run the games via the Quest's internet connection or is it still all through the PC.

    You summed up exactly what I needed to clarify that when you said it essentially makes the PC think a Rift is plugged in. In other words, you use it just as you would a Rift while it is plugged into the PC, and use it as a Quest ONLY when it is not. Which is what I assumed, but I wasn't 100% sure.

    Unfortunately, that isn't going to work for me right now. The PC I had for my original Rift is too old and doesn't even recognize my newer 5G internet, so I can't seem to get it connected to the internet at all. So, sadly Link isn't going to work for me until I can get around to buying a newer VR ready PC. :-(

    I’ve set it all up, plugged in my JOTO USB3.1 cable, the Oculus PC app says it’s connected and active, the popup comes up on the headset asking to activate oculus link, I select enable and it just goes back to the quest home every time!
