A7N8X Deluxe Front Panel USB Won't Work

I have an ASUS A7N8X Deluxe motherboard in a Antec SX635BII. The
cable for the front panel USB connectors is a godawful thing with tiny
individual sockets for each of the 8 pins.

Because of the risk of connecting the pins wrong I did it with a
friend. I determined where each pin should go, he connected them and
I checked to be sure they were right.

Neither front panel connector worked. So, we switched roles -- he
directed and checked and I connected the sockets.

Still, neither front panel connector works.

I've done it all again myself. Still doesn't work . . .

Based on the printing on the tiny sockets they're wired as follows:

#1 +5v red
#1 -D white
#1 +D green
#1 ground brown

#2 +5 orange
#2 -D yellow
#2 +D gray
#2 ground purple

unused ground blue & black wires
[the SX635BII manual says there are only 8 wires but there are 9 or 10
depending on how you count this double]

Here's info from the Device Manager:

I assume the cable is wired wrong. But, both channels?

Anybody else had this problem?

What are you trying to plug into the front ports to test with??

I have the same MB as you and pretty much the same case, I have the SX835II.

All of my USB devices except my USB 2.0 MP3 player worked when using the
front ports. I called Antec and they are sending me a new set of front ports
for the case that are USB 2.0 compatible.

To test and see if the header on the MB for the front ports are working,
plug the USB expansion bracket that came with your motherboard in and test.
If nothing still works then your USB header on the board could be bad.

I've tried a couple of different gadgets (one is a ZIO SmartMedia card reader),
both of which worked on my previous USB 1.1 ports.

But, I didn't know the front connectors don't support USB 2. Does the internal
header support USB 2?

Do you know why one port is called a "Standard Enhanced PCI to USB Host
Controller" and the other two are called "Standard OpenHCD USB Host Controller?"

I guess I'm going to have to do that, but I hate those tiny connectors so bad I
leaving it as a last resort.

The design used on the A7N8X Deluxe has 2 controllers to handle USB1.1
and 1 Enhanced controller to handle USB 2.X requirements. Further
exploration in Device Manager should show 3 "USB Root Hubs", 2 of which
have 3 ports each assigned to them and 1 which has all 6 (USB 2.X) ports
assigned to it. If you have any USB 2 devices attached they should show
up on one of the 6 ports there, otherwise they will only show up in one
of the other Hubs. All 6 should work with 2.0 devices but I've heard
some folks have had problems with some of the Antec cases. If you do as
Jim suggested that should let you know if its the board or the ports.

This is a long shot, but do you have a jumper installed in one of the
two possible positions, on the USBPWR_56 three pin header ? That header
determines which of the two supplies, either +5V or +5VSB is used to
power the +5V leads on the USB56 header, and with the jumper missing
on the USBPWR_56 header, no power would be going to USB56.

There is at least one poster who visited here, who was missing USBPWR
jumpers for some reason.

HTH,
