    Default M3N78D USB 2.0 issue under Windows 7 x64

    I have just installed new o/s Windows 7 x64 Ultimate on my PC
    Loaded drivers from m3n78d suppord CD and done Windows update to service pack 1.

    Every USB device reports issue: "...could run faster if connected to usb 2.0"
    Now I know that all my ports should be 2.0 so the problem must be in Windows itself.
    I have checked in BIOS - USB 2.0 support is enabled.

    M3N78D + Bios 1.6
    Phenom II x6
    gtx 460
    4GB 1600 DDR3

    Please help me to find solution.

    I am having the same problem. USB 2.0 was working under Vista 32 bit. However, once I upgraded to Windows 7 64 bit (fresh install), I get the same message you get. the USB transfer speed indicates that it is running at either 1.1 or 1.0. So far, I have not found anyone with a solution.

    Try to download and install latest drivers:
    ASRock > Products > Motherboard > M3N78D > Download
    (A suggestion only; I don't have that board.)
