Fedora 39 does not detect the Logitech Brio 4k device

Hello. I have never set up a webcam on Linux before, maybe I need to install some rpm packages to make the Logitech Brio’s video and microphone work.
I don’t see anything resembling a Logitech Brio 4k among the devices. This computer has Windows 10 installed, and the webcam works fine on it. The device is connected to a USB 3.0 port.
In a related forum thread, someone mentioned that their Logitech Brio 4k works out of the box on Fedora 38.

ls -l /dev/  | grep video

nothing

Shutdown the computer with the Webcam still plugged in.
Power up and go to Gnome > Settings > Privacy :

@user2021 I cannot find a link to a thread where someone stated this model works OOTB, could you link that thread?

I will try your recommendations a bit later. But I think it won’t help because it says that even if you disable the camera in Gnome settings, some applications will still have access to it. In my case, Fedora doesn’t see the device as if it’s not connected. Here is a link to a post where it says that Fedora 38 detects Logitech Brio, at least the microphone. In my system, the microphone is not detected.

Please try this, with the Camera Plugged in to a valid USB3 port, shutdown the computer, reboot and then straight to Gnome settings. Also, Comparing F37 to 39 is not very apple to apples and Hardware and apps move a lot as to how they are communicating via Portals now.

I tried what you recommended, but unfortunately it didn’t help. Perhaps I did something wrong. I booted into Fedora, the camera was connected to a USB 3.0 port, then I rebooted Fedora and immediately went to gnome settings/Privacy/Camera. The Camera switch was on, but the camera was not working. I tried turning the switch off and on, but it didn’t help.

I also found that other users have the camera working with the uvcvideo kernel module. I checked and found that this module was not loaded.

lsmod | grep -i uvcvideo

Then I loaded this module, it loaded, but /dev/video did not appear.

sudo depmod
sudo modprobe -v uvcvideo

Maybe another module needs to be connected?

Well that suck, and is definitely not an OOTB experience. Since you pointed out that @salimma had the same device, maybe they can chime in and help out. if the module is in the kernel,or you need to get firmware for it they might be able to help.

I found out that the camera on this computer only works on USB 2.0. It doesn’t work on USB 3.0 in Linux, but it does work in Windows. On another computer with a newer motherboard, the camera works on USB 3.0 as well. When connected to this computer via USB 2.0, the camera works without any settings for both video and microphone. However, on USB 3.0 it gives an error(dmesg):

usb 3-1: new SuperSpeed USB device number 111 using xhci_hcd
 usb 3-1: unable to read config index 0 descriptor/all
usb 3-1: can't read configurations, error -71
usb usb3-port1: attempt power cycle

Some usb3 devices are early release and may not be compatible with the latest usb3 interfaces. It also may be the opposite, newer devices may not be compatible with systems that have older interfaces.
