Default USB issue

Hi
I have got 2 USB ports on my mobo(Gigabyte 81875 Ultra) and 2 USB 2 ports.

when i go to my device manager, under "Other Devices", the USB controller shows the exclamation mark.
i checked it's properties and it shows

The drivers for this device are not installed. (Code 28)
To reinstall the drivers for this device, click Reinstall Driver.
Location : PCI bus 0, device 29, function 7

i checked all hour ports with a 256 MB Crucial GIZMO USB Memory STick, and it can read it.
why does it say there is no driver then?
is the problem only with USB 2 devices?

Hi
I just hooked my Sony Cybershot to my PC, and i got the following error

The Unknown USB device is a HI_SPEED USB device and will function at reduced speed when plugged into a non-HI-SPEED port.

There are no HI-SPEED USB host controllers installed on this computer.

I think i will check Gigabyte's websute for the USB host controller.
Any thoughts

I think it might be a Windows XP issue.
Windows XP Pro 2002 might not be supporting USB 2(HI-SPEED)

i will install SP1 and see if it works
what do you guys think?

I installed windows xp sp1 and the exclamation mark goes away. i think it should work with USB2.0 devices.

time to find out if all four of my ports are USB2.0 or just two of them

You HAVE to have SP1 installed to use USB 2.0
