I did cut you some slack. I said you'd get the dumbass tag for thinking about using a replacement ipod for a testing device knowing what happened the last time you tried it. I didn't say you were a dumbass for the initial incident, just for the fact that you considered trying it again using such an expensive testing device. 🙂
One of my cases has one of those annoying messes of individual plugs for the front USB ports. You can bet I didn't test it by plugging in my MP3 player. I plugged in a $9.99 joystick to make sure the ports worked.
So how to fix it. Are you counting the pins right on the motherboard? They generally go like this:
1 2
3 4
5 6
7 8
9
with pin 10 generally omitted to allow the use of a keyed socket.
The order on my VIA M10000 motherboard (the only one I have with one of these on the board) is
1 TPA+
2 TPA-
3 GND
4 GNF
5 TPB+
6 TPB-
7 1394_VDD
8 1394_VDD
9 GND
A firewire socket (with the angled end to the right) is
2 4 6
1 3 5
and the pinout is
1 Power (VDD)
2 GND
3 TPB-
4 TPB+
5 TPA-
6 TPA+
As you can see, it's not 1 to 1, 2 to 2, etc. In the adaptor that came with my motherboard, pins 3 and 4 are shorted in the adaptor's cable. So are 7 and 8. 9 goes to the shield. Also, if you're using a diagram for a cable, remember, that cable flips 180 degrees when you plug it in. If you wired the socket using a cable diagram
1 3 5
2 4 6
that would be a Really Bad Thing(tm). Your power and ground would be swapped which would reverse the polarity and...zap.
