PC won't recognise USB2 ports

[MIcrosoft News Server]

I have a motherboard with a VIA chipset. IT is said to have USB 2 ports,
but whenever I plug in my USB2 dvd RW drive, I get a message telling me it
will function much better in a USB 2 port!

Eventually I bought a new PCI card with USB2 ports and tried that. I still
got the same messages. What am I doing wrong?

What version of XP do you have installed? SP1 or higher supports USB 2
without adding drivers.

It shows that I have an enhanced host controller. When I unplug all other
usb devices my usb2 drive seems to work fine on usb2. If I just have one
other usb1 device connected it seems to slow all the ports down. Is that
possible?

Thanks so much for your help.
