Webcam not recognized

I bought a new USB webcam. It is branded Nabo WBF 2000. When connecting, journalctl writes this:

To me, this looks not ok, and trying with GUVCView justifies, that the webcam is somehow recognised, but it does not work. GUVCView takes ages to start when this camera is connected. Although it provides the model in the device list, by selecting GUVCView says (after a long time):

Guvcview error: Could not start a video stream in this device.

How can I make it work? Is it missing the USB id somewhere entered (sorry I am somewhat out-dated, I cannot remember where to add missing USB devices, because I am sure this camera uses a standard driver).

What’s the output of v4l2-ctl --list-devices?

You can ls /dev/video* to see if it generates a new video device entry when plugged in. I never heard of that brand but even the shittiest cheap from unknown chinese brand webcam is recognized and working well as its spec says.

$ v4l2-ctl --list-devices
webcam: Fullhan Webcam (usb-0000:00:14.0-1):
	/dev/video2
	/dev/video3
	/dev/media1

HD WebCam: HD WebCam (usb-0000:00:14.0-7):
	/dev/video0
	/dev/video1
	/dev/media0

… of which the first mentioned is the non-working webcam.

During the last days, I installed a fresh Manjaro on my new Raspberry Pi 4. There, the webcam worked great out of the box. So, it’s up to me fiddling around with the setup on my laptop.
