Here's another episode in my saga to plug everything into everything else...

Right now, I have the SiK cable with the FireWire and line out connectors hooked up to the power brick and my little stereo in my room. I also have the USB 2.0 cable right beside it for when I need to sync up. (I have a 3g 10 gig.)

I know the SiK cable has full FireWire connection for syncing as well as charging. What I'd like to do is splice my USB cable (with a switch) into the SiK cable to have sync, line out, and charging all independent of each other.

I've looked all around and seen some pinouts that include the FireWire data lines, but not the USB ones. I've noticed that FireWire seems to have two wire pairs dedicated to data transfer, but USB only has one (if I remember correctly.) Anyone know anything about this?
