Look for an "Enhanced" entry in the USB system devices in
Device Manager. That means USB2 has been enabled and you can
check it and see a driver loaded for it. The driver is build
into Windows (like WinXP SP1 or SP2).

This procedure, removes the Device Manager USB entries, and
after a reboot, Windows rediscovers all the USB devices again.

It is also possible for the problem to be caused by the USB cable used.
There are cables which are USB 1.1 only (typically used with keyboards
or other low data rate devices). In that case, the OS will try to use
USB2, get lots of CRC errors and communication problems, then revert
back to USB 1.1. And then you see the message that things could be
faster. A better quality cable might be all that is needed.
