    Question USB / Firewire question
    I am pretty sure I have narrowed down the issue on my iMac to my USB ports being bad or having low power. I do have two Firewire 400 ports that are not being used though.

    Is there an adaptor, cable or hub that goes from firewire to USB?

    Can I replace the USB hubs on my iMac?

    Other options?

    USB and FW are not compatible. There are no adapters that go from one to the other.
    There do exist hubs that have both FW/USB.
    But, beware... they only pass USB to USB and FW to FW, not one to the other.

    My best guess, if the USB has died, it would require replacing the system board - but we should have others much more knowledgeable about this type of repair.

    Their next question is going to be, what makes you think the USB ports have died?
    What model iMac do you have?
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.
