Looking forward. I have not touched the front usb for a while as i was having issues. I have not tested on Lion hopefully it works better.
A special thanks to you. It was one of your earlier posts that triggered the action to trace pins 5 & 7. Before that the USB problem had fallen onto my back burner. Previous investigation indicated that it was a power problem, but tracing the front board isn't easy. Taking meter readings is very difficult since most of the contact points need to be scraped clean. It seems like there is a clear coating applied on the board.
My rig is running the latest Snow Leopard (10.6.8?) . Most everything is stable, so I'll wait a while before making another software leap.
A current project is adding front panel HD audio support. I want a fully functional sensing operation and correct presence indications. My system can run either OSX or Win7, and the audio should work correctly for both. After reading all of the data sheets, it would appear that a true solution is close at hand.

Then I brought up the fire wire ports and audio as described here:
Try to locate an Apple front panel audio cable to mate with the FP connector.
Looking down on the assembly; Left most pin Sense, next Ground, next Left channel, next Right channel, right most pin is shield ground. Cable the ground and Left and Right to your PC Audio header (see your MB manual for that pin-out). Mine worked first try.
And note that the front panel audio done this way is not audio detected... you need to go into the Sound preferences and select the front head phones (assumes you have the correct kext loaded).

My audio is working under OSX now. The sensing wire-up is ready as well. I'll test that under Win7 to verify correct operation.
With that done, it seems like all of the front panel connections are working correctly on my box.
BTW, the Mooner diagram shows the top 5V supply coming from a SATA power connector. During sleep, that power source will turn off, so you won't get a blinking LED indicator. The diagram also seems to leave off the 3.3V connector. Does that affect any of the Firewire operations?

I do not own Win 7 by choice so can not share anything in that area.

Time permitting, I'll draw up a diagram and post the results for others to follow.

Hello, again. After my first post some time has passed. In that day when I wrote the post, I figure out my front USB and audio pins and it worked fine with OSX and Windows. After that a few years later I upgraded my motherboard, and I don't know why, but I did not use my front panel output, maybe I don't need it at that time or something. Right now I need these front panel ports. USB working fine. Front audio does not working any more and I don't know why. Maybe motherboard front audio wiring changed in years or maybe it depends on motherboard manufacture. Maybe operating system changed something with drivers. In the past I have it MSI and now GIGABYTE.
Maybe someone have any thoughts why the same wiring does not working with gigabyte motherboard?
