    USB power question - please

    Hi,

    i would like to know how can i turn on and off a USB port.

    My objective is to turn on a lamp/bulb.
    The USB has 4 wires, i guess 2 for data ; 1 for + and 1 for -
    so i can plug a small motor to make a switch click in a lamp/bulb by coneecting the + and - (pins 1 and 4 i think)

    My problem is how to turn on/off the usb motor.
    Windows have an option to usb power safe, so i guess it could turn off the usb and on again.... but all usb at the same time(?)

    I know i could just unplug the usb, but i want to do it outside my home, like being at work connecting to my home PC (there is software for that) and turn on webcam and also a light in room.

    anyone have an idea on how to do it? without any complicated circuits...
    thanks

    I think it would have to be a software controlled circuit board connected via USB. I don't think individual USB ports are controllable individually because the USB port needs to connect to a USB device so that the OS has a device driver to communicate with the device and its own interface.

    Have a look at http://www.pc-control.co.uk/motorbee_info.htm for some ideas. They have loads of USB control modules and not too expensive.

    If you haven't played a classic game in years, it's never too late to start!

    Are you after a USB controlled relay?

    Alternatively, a powered external hub with something else controlling the power (but then that's another layer of fiddling about).
