I have a computer desktop thats now a few years old. It has onboard an
Intel 82801BA/BAM USB 1 controler. Because I wanted to upgrade to hi
speed, it purchased a PCI USB 2.0 controller, which the system reports
as a VIA Rev 5 or later. From the very start XP refused to recognise it
as USB 2, and I was getting the stupid message "your device can perform
faster" etc, everyting time I pluged ANY USB2 device. I did manage to
find some VIA specific drivers on the internet that appeared to fix the
problem,

Try the card in a different PCI slot

looks like the bios is changing the way resources are allocated.


If that does not do the trick...go the them mfg's website and get the
latest drivers rather then questionable ones you found on the internet.


Perhaps "on the internet" is a bit of a misnomer on my part. I
downloaded directly from VIA website, file name VIAUSB2V270-L. The XP
part of it is in fact a filter driver, which is supposed to "enhance"
the onboard Microsoft drivers.



Ok, then I'm sure you got the correct driver

I'll try shifting it to another PCI slot, and if that does not work, I
think I'll just pay for a new one with a NEC chipset, as I have been
told they are much better.



No guarantee of course but I have seen that work quite a few times
