    Open up Device Manager. ( Open START, type DEVMGMT.MSC ) Click on USB Controllers.
    If any of the listed USB ports are listed as "Enhanced", then you have USB 2.0

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Thanks Bob - but that can't be the whole story. For example I had a pc with usb 1 on the motherboard and I bought a usb 2 card for it, so the same pc had both speeds. (its not that one I am trying to check but a laptop). That's why I was asking if there is any way of checking at the connector end, so you not only know if you have a mix, but also which connector is which speed.

    The easiest way to check an individual port is to simply plug a USB Thumb drive into it. Unless I'm wrong all thumb drives for the past couple of years anyway are USB 2.0. If the port is USB 1.0 you will get the infamous prompt telling you that the device could function faster, etc., etc.....

    Purely as a pedantic note, the most likely alternative to USB 2 is USB 1.1...! USB 2 came out in 2001.

    And it can't be too soon! Do you know how long it takes to write 1.4 TB to an external drive via its USB 2 interface?!

    After reading Dave's link http://www.everythingusb.com/superspeed-usb.html as well as Everything You Need to Know About USB 3.0, Plus First Spliced Cable Photos , I have the following obvservation/question:
    Current External USB 2.0 compliant disk drives can utilize USB 3.0 speeds with a spliced USB 2.0 to USB 3.0 cable ?

    I would say the answer is no. Your external drive has a USB 2 interface, and even if you connect it to a USB 3 interface card you won't be able to drive the disk at faster than USB 2 speeds...
