Determining whether your machine has USB 2.0

Been installing a lot of Stroragecraft disk imaging software onto machines of late. To get the best performance via an external USB device you need to ensure that the machine supports the newer USB 2.0 rather than USB 1.1. How do you know if your machine has USB 2.0? Generally, you'd just plug in the drive and see if it is slow but here's a better way :

    1. Right-click the My Computer icon and select Manage.

      Note: Windows XP users may need to click Start to access the My Computer icon.
    2. Click the Device Manager icon.
    3. Click the plus (+) sign next to Universal Serial Bus Controllers.

      Note: If Universal Serial Bus Controllers is not listed, there is a problem with the USB controller or the USB controller is not enabled in the computer's BIOS. Please contact the computer or card manufacturer for updated drivers and/or for information on how to fix or enable the USB controller.
    • If Enhanced Host Controller and/or USB 2.0 Root Hub Device is listed, then the computer has USB 2.0 ports.
    • If Universal Host Controller and/or Open Host Controller is listed, then the computer has USB 1.1 ports.

You'll find this info here.
