    I've tried...
    1. Different devices in this slot
    2. All other USB slots on the device work
    3. Completely removing power & USB connections from the hub, rebooting system & replugging.

    Suggestions?

    Looks like I bought this item from MP3car back at the end of March, barely over 5 months ago.
    I would repeat those steps on another computer and also try some other devices...just to be 100% certain it is a faulty port.

    have you tried it on a different computer? sometimes USB drivers get confused at the OS level.

    You must have the p5usb plugged into a host device before it gets power. Also please see the technical documentation on the first three links of the product description here if you haven't already.

    How do I get this 12v hub to power on without supplying it an upstream USB connection? I.e. I want it to turn on when +12v is sensed on the Acc wire.
