Solved. "Bus 001 Device 004: ID 0bda:58c2 Realtek Semiconductor Corp." Is the webcam where where 0bda=VID 58c2=PID is the hardware ID. So lsusb sees it. With "dmesg | less" terminal command I searched the camera from VID&PID numbers and i found it, the report says OS see it and initialized it correctly, so it's not a driver problem. I found a website that it sayd the 0bda:58c2 camera is supported for ubuntu 18.04 from the 5.1.0 kernel version. So the problem is the camera must be activate manually from "sudo modprobe uvcvideo" terminal command (it can be added on startup command). Hope this can be usefull for anyone.

Strange thing is that 2 years ago I was using Ubuntu 18.04 and webcam was working. PS: the webcam work fine because I use it on Windows every day and with Windows Hello too.
