I'm having a problem with my KT600-(Via 8237 chipset-athlonxp), not being able to use the front usb ports. It has two hubs in the back and two onboard pinouts for the front-which I'm only plugged into one right now. The back hubs (4 ports) work great. When I plug something in the front it ends up with "unknown device" in the usb section and is disabled. I read about using more than four ports here somewhere but can't remember where. I've tried SP3 and nusb3.3 independently and various Via usb chipset drivers to no avail. Can someone tell me what the problem is?

Sounds like a hardware issue, rather than a software issue since neither NUSB or USP3 are making any difference. Check in your BIOS settings and be sure that no USB devices settings are disabled.

Also be sure that when you first connect a header to the onboard ports that you do not have anything plugged into the header. Do a reboot after connecting the header and before you attempt to connect anything to it.

Properly connected? Found this (your board?) -

Scroll to "Pinouts"...

Or refer to this pic (from the ASUS A7V600-X):

Thanks everyone. I used the site from submix8c and found this diagram. My usb cable only has pins up to pin 8. According to this it looks like I need 9 and 10 which seems strange. I guess I need a different cable.

No.
Pin 9 is "KEY" i.e. it is not connected and used to identify the pins layout.
http://pinouts.ru/Sl...SB_pinout.shtml
A single USB port has 4 (four) pins (just as a USB cable has four wires):

• USB Power +5V
  
• USB Data -
  
• USB Data +
  
• USB Ground (0V)

Those are 1/3/5/7 in the image you posted for first port (USB0) and Pins 2/4/6/8 for second port (USB1).

jaclaz is right (of course!): pin 9 is "KEY", being usually not connected (viz. "NC"), or, less commonly, grounded. Now, pin 10 is absent (= missing), so that one can immediately recognize which pin is pin 9 (because it's the only one that has no conterpart). Reversing "Data +" and "Data -" causes the port not to work, but usually causes no damage, so it can be corrected (this seems to me to be the problem with your machine). Now, reversing "Power +5V" and "Ground" can kill the motherboard, so take care with what you do, and don't do anything unless you're sure of what you're doing!

OK, link I gave has somewhat confusing "acronyms" for Pinout. Dencorso's picture and Jaclaz' link is more "correct". Your Connector has only two items lacking (Pin#9/Pin#10) that are (probably) irrelevant (as Dencorso points out). A "full 10-pin" adapter has a "plug" in the Pin#9 position and an actual "Hole" in Pin#10 position to prevent EXACTLY what Dencorso is warning you about, somewhat akin to the "later" IDE and Floppy cable connectors. BEWARE if your Connector is one of the "oddball" reversed-connector-adapters (like some older Tyan MoBo's).

I'm going to put the MB in other case or install XP and see if it works. right now it has trouble loading the drivers for anything I plug in--code 2 and happily assigns the unknown device from the sp3 inf.
