It will always come back. You have a Firewire port in your system and this comes as part of the setup for it. It does not hurt you or pose any additional load on your PC. If it really bothers you, best you can do is 'Disable it in this profile".
BUT, if you ever have to use your Firewire port you will discover that chances are it will not work properly. See, Firewire does not work exactly as USB. Go ahead and disable it but keep it in mind if you evere use Firewire.
