v4l2-ctl --list-devices -D

Integrated Camera: Integrated C (usb-0000:05:00.3-3):
/dev/video1
/dev/video2
/dev/media0
​

My webcam do not work, tried several different program; Kamoso, Webcamoid and guvcview

Kamoso give me "No device found"

Sometimes the webcam disappears from lsusb and sometimes it is there.
I have Googled at lot, done lot of different things, but nothing seems that helps.

Hope for help here!

Try switching to Plasma (X11)? On a default installation of 25.10, Plasma (X11) isn't installed; Plasma (Wayland) is the default. But you can install it. In a konsole, type: sudo apt update && sudo apt install install plasma-session-x11

Logout then log in, selecting Plasma (X11) at the SDDM Login Screen.
