OK Guys,. I got into the Bios.

One selection was whether to allow Legacy USB 1.1 to be enabled.
I left it enabled.
Another selection was whether to allow Enhanced USB. I changed
Another selection was for USB 1.1 -- its options were None, 1, 2,
or 3 controllers. It was set at three and I left it there.

I rebooted. All USB devices are working.

I checked Device Manager. It says:

Generic USB Hub
Intel 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD
Intel 82801DB/DBM USB Universal Host Controller - 24C2
Intel 82801DB/DBM USB Universal Host Controller - 24C4
Intel 82801DB/DBM USB Universal Host Controller - 24C7
USB Root Hub
USB Root Hub

Here are my QUESTIONS:
1. Why do I have TWO "USB Root Hub? ________
2. How many of my USB ports are set to USB 2.0?
3. What do 24CD, 24C2, 24C4 and 24C7 mean?
4. I have SIX USB ports on the ATX case. Four are in the back
-- same as in the mobo manual and the manual you had me download. the
other TWO are on the right-side of the computere case. WHICH ports
are showing up in Device Manager?
5. Is there a way to plug in a USB "tester" into each port and
check the speed, and find out that way if they are set to USB 1.1 or
to USB 2.0?
7. If I DISABLE Legacy Support for USB 1.1, will my old USB
devices still work?
8. Should I set the USB 1.1 settings to NONE?

9. Do I still have to install a separate USB 2.0 card, as
earlier recommended?
10. Do I still have to install XP Home SP 2 in order to get USB
2.0 drivers, as earlier suggested?

Thanks so much for your patience. It's frustrating for me, but
bit by bit I learn a little more, and get my computer to do what I

Looks like all your Intel Host Controllers are USB 2.0. Enhanced is
the key word
USB Root Hub are your USB 1.1 controllers.
9 & 10 Answer No. If you have too many USB Devices you may need a USB
Powered Hub.


This was a helpful response. Thank you. Despite Jason's insistence
that I need to install SP2 to get USB 2.0 working, I will wait a
while before I do that. I'm making headway on the USB mystery!

You're nice.

Installing SP2 is the easiest way to get USB 2.0 compatibility. That's a
If you don't want SP2, then you'll need to get the files from Asus, if they
even bother to distribute them anymore.

Since SP1 of Windows XP is nearing end of life (for support), it's just
plain easier to install SP2.

Why don't you want to install SP2?

Hello Fishy
If you are still monitoring try the below to everything usb.

They also have a great forum. I asked them a few years ago, what all the
ports etc were about and I got one of the most detailed replies I have ever
had from a forum.
And they have a couple of geniuses re bios settings/updates etc.


Here's another one, Jason:
My earlier posts explained the ASUS did *not* distribute the
drivers, and the ASUS user's guide specified to get the drivers from
SP2 is irrelevant to my question.

You are an MVP -- so you should provide more accurate feedback than
the other posters.
