    Is there any way of making the U S B sockets not powered when the pc is
    shut down.
    Several things i have permanently connected have L E D lights which
    keep glowing away unless i turn the power supply off

    Thanks.

    Older computers have a jumper, with a name like "USBPWR".
    Set to +5VSB, the LEDs stay on all the time. Set to +5V,
    the LEDs go off after your session ends.

    Modern computers lack the "USBPWR" jumper option, and
    they're running from +5VSB permanently. To turn off the
    LEDs in that case, use the switch on the back of the
    computer.

    For more information, see the manufacturer's documentation.

    In this example, you can see USBPWR on PDF page 34. There
    are four jumpers, to control up to eight USB ports.
    Setting a jumper to +5VSB, leaves the LEDs lighted on
    the USB device when the session is ended. The reason
    they have separate jumpers, is so your USB keyboard
    could be powered, while the other ports are turned off.
    That way, you can wake the computer by pressing a key
    on the powered USB keyboard. In this case, one jumper
    controls a USB stack of two connectors.
