Logitech keyboard, latency in media buttons

I have the Logitech Internet Navigator keyboard, very similar to the Elite keyboard, but different color and volume buttons instead of a knob. Anyway, There is a significant 3-5 some times 7 second delay from when I push a media button (such as play, pause, fast forward etc.) Is this a USB issue, or just the drivers taking their sweet time to tell iTunes to do something? Is there anything I can do to fix this?
