No, we can put content on it without "installing it" and use it. And we don't need System Config Tool. This is why I said, it's not what everyone wants when they say USB access.Not exactly like that. You should have the game INSTALLED on the USB device, not simply copied and encrypted....
That will only be possible when we can use System Config Tool (and bypass signature checks).
Most people mean hook it up to pc, put games on it, play/install them, I'd imagine.
