The title should be self-explanatory; My oculus software is detecting my USB 3.0 cable(the Anker one that was recommended before the official link cable) and USB 3.0 port as USB 2.0. I've gone and tried to update my drivers, including uninstall/reinstall, to no avail. Any suggestions for a fix? For reference, both my Quest and PC are running the latest versions, and my PC is link compatible.

Its a known issueTry turning the USB C connection over. Although they should work in both directions, some USB cables only work properly when connected in a specific direction. other than that open a support ticket. https://support.oculus.com/885981024820727/

Hi guys, just looked at this issue, from what I can see the system tells the device what type of connection it gets. Using an app called USB Tree Viewer I was able to start the app in administrative mode, find the host controller the Oculus device was on unplug the Oculus device and restart the host controller. Once I had restarted the controller I then plugged the Oculus device back in to see that the device was on a USB 3 port ( ss - super speed ) and then restarted the Oculus software and then my Oculus software could tell it was using a ss port and worked properly again. I know it's not a fix as such but, more of a workaround. Try the method and see what results you get. If you want the USB Tree Viewer, google it as I can't post url's yet or email me if you get stuck I don't mind helping anyone out where I can. deathssaviour@googlemail.com.Cheers Jon

ok so from what i can gather According to Oculus support there are known issues with the ASMedia chipset with USB 3.1 Gen 2 ports (Not sure if this applies to you you'll have to check in device manager) also some people are reporting that on that chipset if they uninstall the drivers and install the default microsoft drivers the link recognises i as a USB3:edit:also Z370 based boards using the ASMedia chipset based USB 3.1 Gen 2 ports DO NOT work with 3rd party cables, but apparently they DO work with the official Oculus Link cable

I have a Link cable and the port I was using started detecting at USB2, only for the quest. I switched to another port (next to it on same controller) and it connects again on USB3. Never got to a root cause yet since switching to other port on same USB controller resolved the problem.Cable speed at USB2 peaks around 360 MB/s where when on USB 3 I get 2.4 GB/s on the USB connection test in the oculus software. Laptop users may not have as ready a means to switch ports. The port it originally worked with USB 3 on, has a USB SSD that connects as USB3 without a problem. Weird issue to pop up.

Oculus staff have already stated on this forum that the Oculus software does NOT detect the port as USB 2 or USB 3. Oculus (so they say) only reports what Windows says the port is.Apparently, on my PC, Windows changes it's mind on a daily basis about whether or not I have USB3 or USB2. I've been running my CV1 on the same hardware, in the same USB 3 ports, since July 2017. I've never unplugged it, swapped ports changed any hardware, reinstalled either Oculus software or Windows. It always used to show as USB 3, now it doesn't.Maybe Oculus are right. Maybe Microsoft engineers are not capable of detecting USB ports correctly. I'll say this though, since 1990 I've had less problems with hardware and DOS/Windows than I've had with Rift.If leading edge software teams can't detect a port that is required for their hardware to run, and rely on a third party to do it for them, then something needs to change.

do you have a lot of USB peripherals (mouse, keyboard, etc) attached, if so perhaps your motherboard might be being overloaded. If you can't manage to figure it out and you have a spare PCI slot on your motherboard, get a dedicated USB 3.0 PCI express PCIe Controller (there relatively inexpensive)

Nothing else is plugged in. Using a gaming laptop.

:edit:

also Z370 based boards using the ASMedia chipset based USB 3.1 Gen 2 ports DO NOT work with 3rd party cables, but apparently they DO work with the official Oculus Link cable

  I am trying to trouble shoot my oculus quest. i have a asus z370-e mother board with that chipset. with a 3rd party cable. if i restart the pc or the oculus some times it will connect as a 3.0 connection until i click accept in the headset then it will disconnect for a moment and reconnect as a 2.o connection. any tips? i dont want to buy the oculus cable and have it not work as well.

    Same issue here.
    
    I tried USB tree view: If I don´t move the headset is 3.2, port 19, but if I move it, changes to port 3 usb2.1.
    
    ROG STRIX Z490 G.
    
    So I think, in my case, it´s a hardware issue. I will trie with a new cable, this time, C to C.

have you checked on Intel's website for an updated driver.

Since you have a laptop see if you have any slots for PCMCIA card

Update, after checking it out with USB device tree viewer, it looks like my USB 3.0 ports are being detected at USB 2.0 for unknown reasons. It looks like there's some USB 3.0 ports but they seem to just be dummy ports

Hmm ok, on USB device tree viewer can you see the usb(S) symbol, if so then USB3 is detected and might be turned off in your Bios

Reboot &&
Go into your BIOS and look for setting callled XHCI or XHCI Hand off, if it set to disabled or auto, it needs to be set to enabled.
reboot.
hopefully that should sort it.
