I have installed a Logitech webcam. It installed a driver called 'Logitech Mic (Notebooks Deluxe)'. The driver causes my computer to hard power off (crashes it immediately) when I start a cam program (u-Broadcast). I know how to disable and un-install the driver through Device Manager/Sound..., but every time I plug something into a USB port or reboot, the driver automatically re-installs itself. How can I prevent this? Thanks.
