The reason I asked specifically if the USB3 controller was Intel:
Prior to Z77 chipset motherboards, literally *all* USB3 controllers (though they were on the motherboard) are 3rd-party USB3 controllers. Prior to Z77 chipset motherboards, USB3 had not yet been integrated into the Intel chipset.
IOW, If you're using a motherboard older than a Z77, your USB3 controller is a 3rd-party controller.
