I have a new Asus M2N32 Sli- deluxe mobo. All seems to be working fine but in the device manager there is an unknown device. It says "Code 28" for it.

Is there a utility that can identify what the unknown device is?

There is a microsoft information page on this that tells you how to look in the registry to identify it, but the area in the registry that they say to look in "HKEY_LOCAL_MACHINE\Enum\PCI"

but i don't have an Enum area to look in as far as i can tell.

I have that on my Asus A8N-SLI Premium board also. I think there is a utility from the install CD that once installed, the unknown device will go away. Maybe the Ai Booster utility? Basically, if I install all the stuff from the CD, I don't have it. If I don't, it shows up. I don't like all the extra stuff being installed so I just leave it as is

What OWA said. Put the CD in the drive and just do an update driver function from device manager. Let it scan the disc. It might find what it's looking for there.

Unfortunately i've tried that without luck.

I was hoping to find a tool that could identify the device.

Even when i let it use the windows update to find it there is no luck.

The mystery has been solved:

I just read a post on the asus forums that this is from the AMD Live option being enabled in the bios. I disabled it and the unknown device is gone. The newest bios has this option... i guess it's for future use since there isn't a driver for it yet.

I have the 0501 bios. Are you using those or the 0504's that just came out?
