    Hi,

    I develop a UPS device it belong to USB HID class and Power subclass, once
    this device plug on system, and you shudown windows later, it cause windows
    hang on screen "windows is shuting down" for one minute then actually
    shutdown completely. if I unplug it before ask windows to shut down, and
    windows will shutdown immediately without any waiting. I don't know why ?
    this situation would not happen on Windows XP/2000, only on 98/98SE/ME.

    did you have any idea for this condition ?

    Thanks.
