device-manager

My netbook has three USB ports, but when I look in the device manager:

Five are listed. Does this matter in the least (or, why are five listed)? The reason I bring this up:

See, if I know that two of the devices in the device manager don't actually have physical ports, I can disable then and up that percentage on the other three, correct? I'm constantly being told that my devices can perform faster if I connect them to a USB 2.0 port, but this netbook is less than a year old.

Thanks.
