Did you look at the program at all, or just post about it and ask questions?

from the users guide:
Target Machine
Hardware: USB Port Enabled
Software: Windows XP*
*Windows XP is currently the only supported operating system. It is possible that COFEE will work on additional operating
systems, but these operating systems have not been tested, and are not supported.
So obviously it needs to be a windows XP machine you are checking, and you have to have access to the USB port.
