Somehow uhci0 didn't have interrupt, but it managed to find the webcam on ugen0. Don't ask me why. I have attached my logs below. You can see many devices sharing same irq. I don't know what line 2 means exactly, but if it means that my USB-controller was assigned irq 11, it could lock several important devices at once, if IRQs are not handled properly. In new logs uhci0 was found configured on irq 9.
