Blue screen uhcd.sys DRIVER_IRQL_NOT_LESS_OR_EQUAL

I'm getting the following blue screen error message on my
Windows 2000 Pro system:

-------------------------------------------------------
*** STOP: 0x000000D1 (0x00000015, 0x00000002, 0x00000000,
0xEB6AAB46)
DRIVER_IRQL_NOT_LESS_OR_EQUAL
** Address EB6AAB46 base at EB6A8000, Date Stamp 3e25ba6e -
uhcd.sys
Beginning dump of physical memory
-------------------------------------------------------

I am able to boot. But, after I login to any profile, the
screen either displays the above blue screen error, or
flashes it momentarily and then the PC reboots. So I am
unable to work on the machine.

The PC is about 18 months old and runs 24x7 using a 480w
power supply. It has a Celeron 2.0 GHz CPU on an ASUS
P4B533-E motherboard with 768 MB of DDR memory. The
machine has a 100GB IDE hard disk, a CD-ROM drive, a CD-RW
drive and a 3.5" floppy drive. 6 USB devices are
connected, including an HP v40 all-in-one, an HP LaserJet
1200 printer, an OKI C5300 color laser printer, a Mustek
1200 UB Plus flatbed scanner, a 4-port USB expansion
device, and a Toshiba PCX1100U cable modem, on which
internet connection sharing is enabled. Aside from the
built in NIC that connects to a home network switch, there
is another PCI NIC card which is currently not in use.
There is also a PCI modem card for receiving faxes. I
also have an old HP LaserJet 4L on the parallel port and a
Palm V series cradle on the COM1 serial port.

Over the past 18 months, I never encountered this problem,
until today. After booting, if I don't login, other
functions are normal, including accepting VPN connections,
file and printer sharing, and internet connection
sharing. I have been running McAfee VirusScan with auto-
update over the past year.

Does anyone recognize this blue screen error, and have any
suggestions? Thanks for any help with this.

Boot into Safe Mode (press F8 at boot time), then rename
c:\winnt\system32\drivers\uhcd.sys to something else.
You will probably have to re-install your USB drivers later
on.
