The thing is that you build the perfect module according to your sources and capability and that is very interesting to know that this type of system has to be built. This has to work properly and I am sure that it would do that. Tis type of system has to have inbuilt usb ports and that is the main USP of your thing. Dell bios update is there to provide any help related to this.[/QUOTE
He never said it was a Dell system and he should forget adding USB to an iso. Windows will take care of that during the install and later you can download the USB drivers from Asus.
