I've been having this problem for several weeks and can't seem to fix
it.
I have a DFI Ultra Infinity motherboard, Athlon XP 2500, Windows XP.
The motherboard has six onboard USB 2.0 ports that work fine.
I added a four port VIA VT6202 PCI USB 2.0 card about six months ago,
and it worked fine. I then bought another VIA VT6202 PCI USB 2.0 card,
as I needed more USB ports, only this card had a slightly different
number on the VT6202 chip (after the VT6202 there is another number on
each chip). The new card only worked at USB 1.0, and every time I
plugged in a USB device, it would say "High speed device plugged into
non-high speed port" and suggest I plug the device into one of the
ports in bold type that can support a hi speed device.
I think it's possible that the old card's drivers are still in the
system, and have automatically installed themselves for the new VT6202
card, which is a different make, and that may be why it isn't working.

In this picture the first device is the motherboard's USB, with four
external hard drives plugged into it, and the second is one of the PCI
cards.

This picture shows one of the PCI cards, but none of the connected
devices are showing that they are connected, even though they are, and
they are accessible.

This picture shows the USB devices in Device Manager.
I have had SP1 installed since it came out, and have just upgraded to
SP2, but with no luck.
I've taken out the two VIA PCI cards, and put in two NEC based ones,
and they have exactly the same problem. They come up with the same
message about a non-high speed port, so I'm not sure what's going
wrong.
Does anybody have any ideas what I should try? I've checked all the
drivers for the USB cards, and uninstalled and then reinstalled them
from the supplied driver CDs, but that hasn't worked.
