"full-speed" = maximum speed of USB 1.1, i.e. up to 12 Mbit

"high-speed" = max speed of USB 2.0, i.e up to 480 Mbit

So, its right that USB2 cards are already running at full-speed (well, kind of; they are not as fast as the onboard USB1.1 controller) but we all want them to run in high-speed mode.
