OT: Why is usb data many times the cpu hog that firewire is?

Greetings;

Motherboard is a biostar with nforce2 chipset, 2800xp cpu, gig of ram.

I've recently made the observation that while I can view 30fps video
from my firewire equipt movie camera with a minimal cpu hit of 2-3%,
but viewing the video from a webcam on a usb 1.1 circuit takes 30-40%
of the cpu, at half the frame rate.

Do I have something fubar in the usb? Or is this just the nature of
the beast?
