Need advice on modification of USB Plug to fit Header on AK31A

[Herkulese]

I posted this in the General Hardware section but received no answer so I am now posing here.

I have a shuttle AK31A and it has 2 extra USB headers onboard.
I also have a 5 1/4" bay mount [2-USB / Intake Fan] combo unit.

The problem is that the 2 MoBo Headers each have two rows of 5 pins in opposite directions as follows:

Row 1
pin 1) 5v DC
pin 2) Data-
pin 3) Data+
pin 4) Ground
pin 5) Ground

Row 2
pin 1) Ground
pin 2) Ground
pin 3) Data+
pin 4) Data-
pin 5) 5v DC

And the plug on my USB/Fan combo has both sides wired the same direction as follows:

Rows 1 and 2
receptacle 1) 5v DC red
receptacle 2) Data- White
receptacle 3) Data+ Green
receptacle 4) Ground Black
"No receptacle 5 for second Ground"

Also:
The Red 5v receptacles on each side are jumpered together
The Single Black Ground receptacles on each side are jumpered together.

My questions are as follows:
The plug is modifiable, so:
1) Can I simply re-arrange the wires in the receptacles so that they match the pin out on the MoBo?
2) Can I ignore the second ground pin on the MoBo, as the plug only has one black ground wire?
3) Can I ignore the fact that the Reds and Blacks were originaly jumpered together when they were next to each other?

exp. with USB on K7S5A


I find this helpful:
usb info

so just follow the picture. Use multimeter to test if the wire is link right from the USB pin to the actually head.

hopefully i can answer your q
1. yes, sure you can
2. yes, the 2nd "ground" you said is connected to shielding
3. no sure. But my USB header/connector do not connect the 5v and ground.

did you get it to work? I'm getting ready to do the same exact thing and was looking at buying something like this but I was afraid the connectors wouldn't match up to the mobo headers. What kind of USB front panel did you end up getting?

flywneel,

I am not sure of the brand but it is a 5 1/4" bay mount with 2 USB and a 40mm or 50mm intake fan.

I have not made the modification yet, but I plan to do so in the next couple of days.
I plan to simply line up the colors to match the pins on my MoBo header, and egnore both pin 5's on the header as there is no second black ground wire going to the 5th receptical on either side of the plug.

Row 1
_________

1 RED - 5v DC
3 WHITE - Data-
5 GREEN - Data+
7 BLACK - Ground
9 EMPTY - Ground (Shield Only)

Row 2
_________

2 EMPTY - Ground (Shield Only)
4 BLACK - Ground
6 GREEN - Data+
8 WHITE - Data -
10 RED - 5v DC

If anyone has any comments at all on this issue, I am still looking for more info.
