No idea since when this happened, I just tried my webcam again, and it is only "partially" recognized.
I get it as audio recording device, but not as video device in systemsettings. Other apps don't recognize the webcam either.

First I thought uvcvideo probably isn't loaded, but see there:
~$ lsmod |grep uvcvideo uvcvideo 86016 0 videobuf2_vmalloc 16384 1 uvcvideo videobuf2_core 40960 1 uvcvideo videodev 131072 3 uvcvideo,v4l2_common,videobuf2_core media 20480 2 uvcvideo,videodev usbcore 200704 8 snd_usb_audio,uvcvideo,snd_usbmidi_lib,ehci_hcd,ehci_pci,usbhid,xhci_hcd,xhci_pci
dmesg schows the following

So I checked if Skype can find the camera, and see there: Skype gets a picture. Why does KDE not recognize the camera?
