There are similar codes where the usb won't talk with a Nvidia video card or a sound card,
So as a guess, the iSO is asking for information from the computer and either its not getting one or its getting conflicting ones,
You do not need a hard-drive to run an ISO "live" so we can discount that, but it will need graphics and possibly sound,and internet it will also need enough Ram and a working CPU, All i can suggest at the moment is if you have discrete sound/graphics cards try cleaning the connections [same with ram]
