That's entirely irrelevant. It doesn't matter how the USB device gets its data; you could have a mainframe connected via USB OTG, and it wouldn't make one iota

That's entirely irrelevant. It doesn't matter how the USB device gets its data; you could have a mainframe connected via USB OTG, and it wouldn't make one iota of a difference because USB does not have DMA.
