I have an Ipevo usb camera and since the last kernel update the camera doesn't work...

Product: P2V Point 2 View USB Document Camera

OS: Linux version 5.3.0-40-generic (buildd@lcy01-amd64-024) (gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1)) #32~18.04.1-Ubuntu

usb camera well detected but uvc kernel driver not loading. There is no /dev/video0 file created. here is the result of "dmesg | tail" command :
