OK Guys,. I got into the Bios.
============================================================
BIOS & MY CHANGS:
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
it to ENHANCED.
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:
UNIVERSAL SERIAL BUS CONTROLLERS
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?
============================================================
AFTERTHOUGHTS:
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
need.

I HAVE the manual for my motherboard. Someone on this list told me to
look in device manager for "enhanced," which would indicate USB 2.0.
Another told me to look for the EHCI entry and update the driver to
bring the ports up to USB 2.0 standard.
The motherboard says I have 2.0 ports but need to get the drivers.
That was published in Nov. 2001, but the mobo was installed on Aug.
2001.
Later, I applied SP1 to XP Home. The USB 2.0 drivers are included in
SP1. Somebody on this list told methat I do not have USB 2.0 ports
because they weren't available in 2001 and that I need to buy a USB
2.0 card.
As you see, I've been getting conflicting information. I need to
figure out
1. Do I have USB 2.0 ports? (yes, because the ASUS user's
manual says so).
2. Do I have USB 2.0 drivers installed?
3. How do I find out if I have USB 2.0 driver's installed?
4. If they aren't installed, how do I install them?

Squire,
Just because a USB Root Hub is present in the Device Manager does *NOT* mean
that it has High Speed USB (USB 2.0) Support. I have a USB Root Hub and do
not have USB 2.0.
How to Check for High Speed USB (USB 2.0) Support.
The Keyword is Enhanced.
Open the Device Manager...
Start | Run | Type: devmgmt.msc | Click OK |
Click on [+] Universal Serial Bus controllers |
If your Device Manager shows an ENHANCED USB Host Controller, the system has
High Speed USB (USB 2.0) capability.
The key word is ENHANCED. If you have an ENHANCED USB Host Controller then
you have High Speed USB (USB 2.0)
All other types are USB v.1.1
