This happens because the actual hardware support on the board may not be physically connected to ports on the notebook. Another example, is that some mobile Intel notebook chipsets/BIOS will show a support for RAID even tho there is only 1 SATA port. Its the same idea. To see if your ports are USB 2.0, instead of 1.1, plug in a USB 2.0 device (usually a UFD) and see if the "your device could perform faster" tooltip. If you get this, you have USB 1.1. If you don't get this, you have USB 2.0.
