camera: no camera at index 0

Hello

I have a problem with cam2ip.
When I run it gives me the answer camera: no camera at index 0
webcam visible through lsusb and support uvc:
|__usb1 1d6b:0002:0310 09 2.00 480MBit/s 0mA 1IF (xhci_hcd 0000:00:14.0) hub

I also tried using -index 1(2,3,4,5...) but it gave no result.
I tried to plug the webcam into other USB ports, but it did not help.

I guess that is on Linux, with OpenCV build or native v4l?
