The E510 MotherBoard has a USB header, It has 9 pins divided in to 2 rows, one 5 pin, one 4 pin. But dell uses a proprietary pin assignment spacing. The "X" look something like this (note: the position of the missing pin on second row):
Dell X X X X X Common X X X X X
Motherboard X X X X Motherboard X X X X
I tried to contact Dell tech support, who gave me 2 weeks run around and finally said the pin assignmnets are an engineering secrect, and they can't tell me.
Does anyone know the pin assignment or know how I can find out?
