If you plugged one chord and it is not easily read by the port, it might be 1.0. To test further, plug the extra chord into the next USB port (now you are plugging both cables into two ports) and if it suddenly works, then definitely you have 1.0 on your machine.

And when you are plugging the mass storage device to a USB1 port, it cannot supply enough power to spin the hdd head properly (if you listen you will hear clicking noises inside the hdd). When you combine the powers supplied by two USB1 ports, then hdd head can spin properly. That is also the reason why some USB chords have two cables split at the end.

USB in the front is actually an extension feature of the motherboard. It is linked via cables which is mostly part of the casing onto the motherboard. Sometimes, the best way to determine the components installed on your machine is to personally look inside the motherboard and see the markings there.

If I remember correctly, the extended USB ports on the motherboard have an option of being USB1 or 2. So my advice is to look inside the motherboard and see where that cable in front is connected.

Those at the back, I will presume that those are all 2 being one is already 2.
