I have a MSI 915P Neo2 with a P4 3.0 lga775

I have built it. THe problem is, all the usb connections aren't working. The ones which are stuck on the motherboard/on the io shield and also the ones I installed myself, which are connected to JUSB2 and the LED connector. I am very sure the USB connection is correct. And the problem si not the thing where the 10th pin isnt supposed to be there, it doesnt have one. So what is wrong?

When you look in Device Manager, do you see any ? or !

It doesnt even have Universal Serial Bus there, like they dont exist

Any "unknown devices" showing up in device manager?

On my Win98se system...
When I...
View Devices by Type

and...
View Devices by Connection
And expand the tree [Numlock + *, then Numlock again]

Is it USB enabled in the BIOS?
