USB 2.0 external drive and PCI USB 2.0 card run at USB 1 speed!??

[Russ]

I just put a PCI USB 2.0 card with 4 ports into my older Windows XP Pro SP3
computer today to get faster transfer speeds to my external drive for a
backup. The computer had only 2 usb 1 ports before. When I turned my computer
on XP added to the device manager: 2 USB Root Hubs, 2 VIA REV 5 or later USB
Universal Host Companion Controller, and a VIA USB Enhanced Host Controller.
I then plugged in my External Drive in, and XP notified me that: "This device
can perform faster if you connect it to a Hi-Speed USB 2.0 port. For a list
of available ports, click here."
I tried plugging the drive into all the USB ports on my computer and got
this message every time! How am I supposed to get my USB 2.0 External drive
to run at full speed?
I looked at this page: http://support.microsoft.com/?scid=kb;en-us;312370
but I don't see why it is a problem since I have SP3...

Have you tried reinstalling your external HD driver?

You may need to get XP to reset the drivers. USB 1 annad USB 2
drivers can get into conflicts when a PCI USB 2 card is added.
Disconnect all USB devices and clear out the USB devices under Device
Manager. Reboot and XP should re-install the USB drivers correctly.
