hi,
I have a somewhat similar problem and was hoping for some help. I have a
Dell Dimension 8250 running WinXP Pro w/ SP3. The system has 512 MB RDRAM.
Lately what's been happening is that whenever I plugin a usb thumbdrive or a
ub hub into the computer, either the computer won't recognize it or the
computer will slow down dramatically. The CPU will be pegged at 99 % and
the computer will just drag in doing the most ordinary of tasks, such as
switching windows. In Device Manager, the USB hub/controller have yellow
exclamation marks ... I have tried multiple times uninstalling the problem
usb controllers and rebooting w/o any resolution. The problem occurs no
matter which USB port I'm using on the computer. Here's the USB info from
my computer:
USB Controller VIA Rev 5 or later USB Universal Host Companion Controller
USB Controller VIA Rev 5 or later USB Universal Host Companion Controller
USB Controller VIA USB Enhanced Host Controller
USB Controller VIA Rev 5 or later USB Universal Host Companion Controller
USB Controller VIA Rev 5 or later USB Universal Host Companion Controller
USB Controller VIA USB Enhanced Host Controller
Any help would be much appreciated. If needed I can post more detailed
description of my h/w.
 
you might start to
analyze the issue
with your cmos/bios
settings.

double check them
and the home site
for your motherboard
to ensure that the bios
is up to date as well.

I figure that the USB drivers got corrupted somehow ... but how do I
reinstall them with a known good version? Simply removing and letting
windows redetetct doesn't do anything. Also the computer will take a long
time to boot if the usb ub/thumb drive is plugged in ... so it's not just
when Windows is running.

In Device Manager, under "Human Interface Devices" the USB receiver has an
exclamation mark through it. Also under Human Interface Devices are my
wireless mouse and my keyboard, both of which work fine. I removed this
entry and also removed all the USB controllers until my mouse stopped working
and then rebooted the computer. When I rebooted, windows tried to reinstall
the USB receiver but errored out. I downloaded the standalone USB driver
from Microsoft's website, but that only applies to SP1 and I have SP3.
When I plugged in my usb hub, windows immediately detected it ... and then
after a minute, my computer slowed down to a crawl. As soon as I removed
it, started working fine. This is happening with 2 separate usb hubs.
Would reinstalling SP3 be of any help?
