The Hi6220's usb controller is limited in that it does not support "Split Transactions", so it does not support communicating with low-speed and full-speed devices behind a high-speed hub. Thus it requires a quirk so that we can manually drop the usb speed when low/full-speed are attached, and bump back to high speed when they are removed.
