Did I kill my mb?

[dabaerman]

firstly, I have a few USB brackets and I notice they are not all wired the same. example A. with the vcc at opposite ends . B. with vcc at the same end. would/could damage occur when using A on a MB with B? I think it did a number on my EP-8NPA SLI.
pictures of the two pin-outs cannot be uploaded because they're too big! so, A. for USB2.0-Ports 5/6;
1 USB+5V 2 USB+5V
3 USB P5- 4 USB P6-
5 USB P5+ 6 USB P6+
7 GRND 8 GRND
10 NC
B. the other that I believe is USB1.1;
1 VCC 2 GRND
3 NEG 4 GRND
5 POS 6 POS
7 GRND 8 NEG
10 VCC
so I plugged B onto MB A. now MB A doesn't post. spins the fans but no drives, CD or HDD. me thinks it is dead now.

I've done the same thing, I lost the usb output on the two external connectors but the usb in the I/O section still functioned. I imagine it would be possible to kill the board.

It's possible you might have killed it. Depending on how the sockets were wired, you might have wired VCC and Ground together.

may have done that. will get more details later. thanx,

Continuing the saga of my misadventures with USB, I managed to wreck a pen drive by using it to test
my front panel USB. now not recognized by XP. of course I thought about backing up the
drive, as I was plugging it in. any chance for recovery?

The other issue was cleared up by purchasing a new case with all the right USB cabling and a new mb.

Glad that it was an inexpensive fix. Yeah, right!

We all have our missing thumb nails and split lips, sorry ya got brused here.

Good to know...
Why would USB have different wiring?
I have read several times in motherboard manuals to never plug a USB into the 1934 port on the board, but I don't think thats what Dabaerman is referring to?
I don't ever want to fry my motherboard this way?

[Gizmo]

USB does not; a USB plug of a particular type will always be wired a particular way. The problem is that when you are dealing with the motherboard headers, you aren't dealing with a USB plug, and the mobo makers are free to pin the header out any way they like. Being mobo makers, they tend to do just that.

on that note: MSI motherboard headers, USB 2.0, are pined out differently on different socket A boards.
I have the backplane headers to prove it and some pics later.

This is exactly why many case manufactures provide the USB header plugs that go to their front-panel USB connectors as a set of labeled single-pin plugs: you look at your mobo manual and plug the appropriately labeled plugs into their respective header pins on the mobo. This makes things a real PITA for the average Joe building a computer, but it's really the only option for case manufacturers in a world where mobo manufacturers can't agree among themselves (or even among different models from the same manufacturer, apparently) as to how the pins should be assigned.

you are correct! the individually labeled pins are a PITA. as I didn't have the original case wiring,
and I THOUGHT I could make one to work, I managed to kill a damn good board. oh well.

I think, again think, that that is not the case (no pun) anymore. I have put together dozens of computers over the last year and they all seem to have the same pin out on the board.

[booman]

Now I'm going to pay special attention to the headers before plugging in the USB cable.
Is there a specific standard for the color of wires to each pin?

[Redroar]

I don't know of a color standard. They usually just have a little writing on them to indicate which they are. And if you just write down the color coding on a piece of paper you can figure it out from there. Funny how we have USB as a great standard, and yet the headers for it are so varied, with no standard.
