Oh, and yes Hans that looks like you should be able to talk to it at
2.0speeds if everything about the device you are connecting to it are
2.0 AND hi-speed (not all USB devices are).

Also, the word Enhanced in your
00:1d.7 USB Controller: Intel Corporation 6300ESB USB2 Enhanced Host
Controller (rev 02)
also usually is taken to mean 2.0 without even the USB2 right before it.  In
M$ the Enhanced is one of the few indicators.
