Using CD boot Disk for Ghost 2003 with External USB Drive

Hello Everyone,

I got this disk from my IT guy to use to image all my computer.  I have about 9 computers and it has only worked on 4 of the computer.  On three of the them I can get into the program, but then I lose my keyboard and mouse(I can't type anything after I enter the program).  The three computer do not have PS/2 ports, so the keyboard and mouse are USB.  On another one, I can get into the program, but can see my Segate 2.0 external USB drive. The other one I might have figured out.  Has anyone run into this problem before.  The three computers are all different Dell computers if that helps and I am running Windows XP service patch 2.  Thank you for your help.
