USB problem which is driving me N U T S

[botox]

I've build this rig and everything works but one thing:

USB ports will not function.
I've downloaded and installed the latest drivers, I tried the ones from the cd, I resetted the bios, I enabled all USB options, I installed different kinds of slipstreamed OS (Windows XP+SP2), I checked if the USB equipment works on my girlfriends computer (which it does) and I am at loss.

I really do not know what to do. Only thing I can think of, is that the motherboard is faulty.

For example what happens when I plus a device in: with a (cheap) laser mouse (no drivers needed!), the mouse briefly (half a second) lights up and then nothing. In device manager the ports show up as working and it is driving me crazy.
On my girls pc it works normally, like it did before on my old PC. My tablet doesn't work, my USB HDD connection doesn't work, my printer doesn't work, nothing works on those damn USB ports.

I really need you help guys.

Is it a new build? Did it work before?
If you go in Device Manager, do you see any flag that a device is not working properly?

I guess you did all windows updates. Anyway it should work without any updates???

Did you check your BIOS version? Latest one?

Go to device manager, double click on each usb controller one at a time and select roll back driver, then reboot computer. They should work now.

Yes, it's a new build, so I don't know if it ever worked before. I did however had the impression that the box was opened before. The box itself was torn at one point and one SATA cable was removed from its packaging.

In device manager it shows no yellow flags. All components are working.

I think the mobo is broken. Under Ubuntu the mouse or any other USB device on any of the USB ports will not function.

RMA.

Yeah, return it. A simple installation of XP should work, even without SP1 or SP2... May be they were aware of that problem and try to find someone who will not complaint!
