USBPORT.SYS is using all the CPU capacity

[bmurf]

Hi,
I've searched the threads and didn't find any solution to my problem.

I have a HP Pavillion a1267c running Windows XP 2005 Media center
Edition with Service pack 3.

When I boot up my USB ports don't funciton. Some of them supply power
but there is no recognition of the devices plugged into them.

When I run Process Explorer it shows "System" (Not "Sysytem Idle") as
using between 96 - 100% of CPU. When I right click on properties it
shows USBPORT.SYS as the thread/process that is using all the CPU
percentage. I can Disable USBPORT.SYS and my CPU usage drops to 5%.
But USB's are all unusable.

I installed a USB PCI card and its USB ports function fine (even after
i disable USBPORT.SYS). My problem is that everytime I start/reboot, I
have to go to Process Explorer to disable USBPORT.SYS or my CPU is
consumed by it. I'm ok with this workaround but others who use the
computer can't handle it well.

I've gone to HP, Windows, and the other component web sites and
downloaded whatever updates I can.

I've uninstalled the USB ports via Device Manager (in regular and Safe
mode) and rebooted - all to no avail.

Any help would be great.

There's a GPO that disables that driver. However there is a trojan codec
that creates an autorun.if file in all devices & drives from a to z. It runs
applications like c:\cb.exe. Info can be found here:

Bmurf,

The above is based on a Microsoft article
(http://support.microsoft.com/kb/555324). If you use the Petri link to
download then you won't even have to create your own ADM file. Just save it
to c:\windows\inf folder thenadd the policy in the Group Policy Editor -
