    Hello, is there an option to enable one of my four USB ports for a few hours (and disable at the other time) ?
    I have a fan behind of my iMac (Mavericks) and I want it work only for 3 hours at the afternoons.
    The reason for all these is that somedays I forgot my fan and he works all day or not works at the time who I want to works.

    You might be able to disable ALL of them by unloading IOUSBmassStorageClass.kext, but there's no ability to do it on a port by port basis.

    I don't know how handy you are with hardware or electronics, but the simplest way to do what you want would be to use an AC fan with a cheap kitchen timer.

    Yes, that's what I'm trying to do now, thanks.
