Unetbootin not installing proper touchpad and mouse support in bootable USB

[Rialler]

Creating a bootable USB with unetbin to install Ubuntu 13.04 let me without touchpad and mouse support, which was working on a live session for my system. Creating instead the image with 'Startup disk creator' worked perfectly
