definitely, just like the S4, or a host of other controllers. But he cant' say "or any controller like it", when he's just talking about ones with the ability to plug in for a slight output boost and maybe some brighter LEDS.... For example A mixtrack is fully USB-powered, and it's definitely a "product like it."
That's assuming it can function on just USB power, just with a lower output volume/LED brightness.... I'm going to laugh my ass off it can't.
