USB Ports not working. NT KERN.VXD not loading. Code 2

My USB ports are suddenly not working.  The yellow exclamation point indicates the NTKERN.VXD device loader for this device could not load.  

USB Root Hub
Device type: Universal Serial Bus controllers
Manufacturer: (Standard USB Host Controller)
Hardware Version: Not available

Device status:
The NTKERN.VXD device loader(s) for this device could not load the device driver. (Code 2)

To fix this, click Update Driver to update the device driver.

>>When I do this, it automatically identifies the best driver location to be: C:\Windows\inf\usb.inf

>>Then it looks for usbccgp.sys (I direct it to c:\windows\system32\drivers) where it finds the file and appears to update, but returns to the same status Code 2 listed above.

I reboot.  No changes have occured.  

What should I be doing?  Is there a place where I can download new drivers?

Thanks for your help.

Thanks Sorgie.  Following the link and the instructions appears very straight forward. However....

For me I was stopped at the Startup Disk.  I was able to find  aspi2dos.sys in the Windows\command\ebd directory, but none of the following (asked for by the Create a Startup Disk process) were found anywhere on my system:

autoexec.ebd
comand.ebd
config.ebd
extract.ebd
fixit.ebd
himem.ebd
ramdrive.ebd
readme.ebd
setramd.ebd
winboot.ebd

There are no *.ebd files on my system.

Beyond that the trhee files I need to replace are not on the ME CD.  All three are on the system in the
C:\Windows\System32\Drivers directory.

uhcd.sys
usbhub.sys
usbd.sys

Any suggestions on what is going wrong here?

Thanks.

Thank you again.  All went well with the advice listed.  Although, I believe the problem was resolved when I found that my system had two System32/Drivers directories.  One was in the Windows directory, the other in the programs directory.
 
The latter had 80 drivers, the other had 55.   I copied the missing 25 drivers to complete the driver directory in Windows/System32.  Then I deleted the USB Root Hub in control panel and rebooted.  All drivers came up working perfectly.

I have no idea why or how I would have ended up with two System32 directories and a partial driver directory, but that seemed to be the problem.

Thanks for the help.
Great glad it's fixed!!
