Ghosted Dell Optiplex 760 Image, USB keyboard and mouse won't work?

Hello All,

I've created a image of a Dell Optiplex 760 by the following steps:

1)   Installed a fresh copy of Windows XP Profession Service Pack 3.
2)   Installed all updates from Microsoft along with all buisness required programs.
3)   Used the answer file creation wizard to ask for PC Name and Admin Password.
4)   Syspreped the machine using Mini-Setup option then Reseal and shut down.
5)   Once the PC is shut down I used a netboot disk to get into ghost to create the Image.  We're using Ghost 11.0.
6)   After the image is finished creating I boot the 760 back up, it proceeds into the mini-setup with out issue, I'm able to progress through and get into windows with no problems.

My issue is when I drop this freshly created image onto identical 760's it'll hit the mini-setup and I won't have any Keyboard or Mouse support.  They are totally unresponsive and no amount of unplugging and replugging them in to different points yields different results.

I've also verified there is no pertinent settings in BIOS which could have an impact on this.  Does anyone have any idea's about this?  I thought perhaps the drivers to let the keyboard/mouse to work weren't properly being packaged during sysprep, but if that were the case the Base machine should have the same issue upon booting into the mini-setup.

I appreciate all suggestions

Thanks,
Garrett M.
