Logitech QuickCam 4000 Pro halts system

[Vasilis]

After switching from Fedora to Ubuntu (17.10 and now 18.04),
whenever I plug my Logitech QuickCam 4000 Pro USB webcam
and I start vlc or any other camera capture program, the memory of
the program increases to maximum, as a consequence the system halt
and the only way out is to reboot the machine.
