    On what specific MacBook Pro?
    Have you tried different USB cables and devices and ports?
    Have you taken a look at System Profiler > Hardware >> Universal Serial Bus?

    It's a spring 2009 unibody.

    Tried many different devices/cables on both ports.

    Not sure what you meant by looking at system profiler, here's a picture.

    Do a SMC and PRAM reset. If you have never done these before the instructions are below. If they don't help try doing each a second time, on occasion that works. Finally if these resets don't help then restart in SAFE MODE and try.

    SMC RESET

    Shut down the computer.

    • Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

    • On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

    • Release all the keys and the power button at the same time.

    • Press the power button to turn on the computer. *

    PRAM RESET

    • Shut down the computer.
    • Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step
    • Turn on the computer.
    • Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    • Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    • Release the keys.

    Ok did those things. Unlike the 2nd restart for the PRAM reset I didn't get confirmation that the SMC worked because nothing happened but I did it exactly as written.

    No change. iPod realizes it's connected to a source of power but the laptop doesn't know it's there. Same with a digital camera.

    Did them twice. Will try safe mode now.
