100% CPU use when new usb device plugged in - services.exe / Windows Server 2003

100% CPU use when new usb device plugged in - services.exe / Windows Server 2003

On my server I am trying to install a new usb drive but all that happens is that the system starts using huge amounts of processor cycles with services.exe. On closer inspection with process explorer there is a thread called umpnpmgr.dll using most of the services.exe processor time.

"You better first install your drive then plug it to your system and some times need to close ot off you antivirus or firewall then install the driver and then plug your device.
and sometimes you must install in safemode for better work.
but the my advice is don't plug device first and after that want install Driver."

"Some ideas:

Check in Device Manager, Properties of the USB device, whether Windows will agree to do Rollback Driver.
Try to delete the USB device from Device Manager and reboot (better do a system backup first).
Try also to disable the USB controller to see if this stops the driver update.
Did you try to take the USB device out and reboot? It might simply be that the new device is broken. You might try it on another computer and a newer OS than W2K3."
