I think for the most part, any particular unit will either work using only bus power, or it won't. For example, my Korg padKontrol works fine on USB power, but also uses a power supply, which I never use. There's no performance difference using it with the power supply. But if I were to use it on an unpowered hub, or a powered hub with too many devices sucking power from it, I'd use the power supply.
