With help from EE I got another USB pinout problem solved - even got both front USB sockets working.
By finding the 5v+ with a voltage tester I'm a bit further advanced but I can't identify the rest.
It's a 6IWF rev 1 mainboard. I found a pdf file for this MB at
Great file but it isn't the same mainboard!!! the USB pinout is different and not in the same place. There are other differences too. The author disclaims all responsibility - he's right!
This pinout looks quite classic but the blank is on the other side
5v  x  x  x  x
x  x  x  x
(the gap is the guide for the original USB plug)
The 5v pin is the first one on the top row on the left - there is only one...
I've tried the obvious things Red, White, Green, Black starting from the 5v pin and I've tried the green and white connectors on several different places.
Is there a "REALLY" comprehensive tutorial with "ALL" possible pinouts?
Otherwise can someone point me towards the real plan of this MB
Thanks in advance
