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.
