The USB ports are not functioning as 2.0
When I plug any USB device in, I get the message IN ITALIAN LANGUAGE
"This device could perform faster if you connect it to a high speed USB 2.0 port"

I've got WIN XP Service Pack 2, with the latest updates.
Also the 6.70 nforce4 drivers, and the 7.0 Bios update.

Any ideas?  :wall: :wall: :bonk: :bonk:

I don't know your board, but in my Neo2 Platinum the normal onboard ports are normal USB; the USB2.0 ports are situated in the d-bracket.
Hope this helps,

Hans

That's not right .
Onboard + JUSB connected usb ports are all USB2.0 and USB 1.1 at the same time if both usb 1.1+2.0 is enabled in BIOS .
Later bioses has only disabled & enabled instead of the old way.
I have two USB 2.0 external drives so i have this verified .
The ECHI controller supports USB 2.0 support for 8 ports . And Each OCHI controller (you will have two of them) support USB 1.1 operation for 4 ports .

antonio , look in devicemanager , on the toolbar select  view - devices by connection
Expand ACPI xxx processor PC - Microsoft ACPI Compiant system - PCI bus .
Now you can open the EHCI controller (Standard Enhanced PCI to USB controller) (Usb 2.0)  and the USB root hub under it and see what devices that runs from the USB 2.0 controller .

Yep, you are right - that is indeed what the manual is telling me. But here they will not show up as USB2.0 in devicemanager, though  ???

Well , is the connected device a true high speed USB 2.0 device.
The term full speed USB is USB 1.1 (12MB/s) and is often mistaken for 2.0 .

In antonio's case I think it's one of two things :
1)MSI have again a bios with only USB 1.1 controllers enabled which antonio have loaded.

2)The Xp native "Standard Enhanced USB 2.0" drivers is screwed up .
Possible faulty installations are :
a: Installed USB drivers from motherboard CD
   (not to be used for W2K/XP , only for Win9X/ME)
b: Installed Nvidia Chipset drivers before XP servicepack
   Nvidia Warns :(Windows XP users must install Service Pack 1, at a minimum, prior to attempting to install this package. )
                      ( Failure to do so will result in the inability to  support USB 2.0. )

c: Some other windows/driver corruption .
