    No, it hands off the usb 1.1 devices to the usb 1 core inside it. This
    is either uhci or ohci, depending on your controller chip.

    Unless you put a USB 2.0 hub in front of a usb 1.1 device, then it gets
    more complicated, but we'll just ignore that issue for now...

    What does /proc/bus/usb/devices show for this device?
