Hi, I have a Dimension 5100. I'm trying to connect a media card reader to the motherboard but the Dell motherboard has a non industry standard USB header. I can manually adjust the connection if I can find out the wiring specification. Intel standard is: +5V■ ■+5V D-■ ■D- D+■ ■D+ Gnd■ ■Gnd S-Gnd■ Dell F_USB looks like: ?■ ■? ?■ ■? ?■ ■+5V (found with multi meter!) ?■ ?■ ■? Can anyone help fillin the missing ?....
