    My motherboard manual states USB 1.1
    Is it possible to upgrade to 2.0 ?

    But be careful.

    In a twist of marketing, USB 1.1 (11Mb/s) got renamed to USB 2

    So now there's 11Mb/s USB2 and 400Mb/s USB2.

    You don't want low speed devices on your (real) USB2 bus, so it's
    worthwhile having a slow USB bus for mice, modems and other cruft.

    The motherboards usb ? No.

    You will need to buy a USB 2.0 PCI card. Make sure it does 400mbits/sec
    though. (might be 480).

    When the version 2.0 spec of USB came out, it had 3 speeds in it, low, full and
    high, the previous spec (1.1) only had low and full

    therefore its totally correct to say that a device is usb 2.0 complient when it
    only supports low speed, what you want to look for is high speed usb.
    Unfortunatly mo-bo manafacturers decided to call the ports USB 2 and people got
    confused.

    Not really an issue, the controler will put it on the appropriate root hub based
    on the speed that the device is.

    Yeah, it's 480Mbps for USB2.0. Firewire is 400.

    IEEE1394b is 800Mbps. I wonder when Intel will feel the need to come
    out with USB3, to try and take another shot at 1394's vastly superior
    technology (given that the 1394 spec allows for, IIRC, up to 1.6Gbps).

    My system info thingy says mine is a 'USB v2.0, 480Mb/s' controller.

    I've not seen a USB 1.1 controller refered to as USB2 before...

    If this is a desktop - buy a usb 2.0 PCI card.

    And yet real-world tests regularly seem to show that USB2 devices are
    slower than FireWire ones.
