    How to tell if you have USB 1.0, 1.1, or 2.0

    I was wondering if there is a way in Windows (at least in XP) to tell what kind of USB ports your motherboard has. I thought I could go into "dxdiag" and find out there, but it didn't specify. I tried the "device manager" and it still didn't specify. I was wondering how I can tell what mine are (without checking the montherboard manufacturer's specs, of course).

    Thanks.

    Open up Device Manager, then expand the Universal Serial Bus Controlers section. If you see items there referring to an "enhanced" PCI to USB host controller (like Standard PCI to USB Host Contoller, or XYZ PCI to USB Enhanced Host Controller) then you have USB 2.0 support.

    The P4R533-N doesn't have USB 2.0.

    Out of curiosity, I opened up my device manager and only one of the USB controllers state "enhanced". Does that mean that only one of them is 2.0 or are they all. If only one is 2.0 compatible, how do I know which one?

    You should only have one entry for an enhanced controller irrespective of how many USB2 ports there are.
