My 80XV Lenovo ideapad 320-15AST has Lubuntu 20.04.1 LTS version, with kernel 5.4.0-49-generic. I have used lsusb but the command doesn’t recognize it; its enable (but not recognized for the system) with the command sudo modprobe -r uvcvideo && sudo modprobe uvcvideo (impossible with key combination) and with the command sudo dmesg -Hw appears in terminal. The system doesn’t recognize it anyway.
This user is in the Spanish group. tells us that in 18.04 it works correctly. We suggest to check another more modern kernel to see if it is a bug
