    i have a macbook pro early 2011, and a dell u2412m attached via mini display port to display port. monitor works fine, but, the monitor's all 4 usb don't work at all, no idea why. monitor comes with a cd for drivers but that's just for windows, seems there's no osx drivers, or apps, nothing. so i wonder, maybe is the display port? should i use dvi? or all usb are dead.. any ideas? help?

    Have you plugged an A-B USB cable from your laptop into the monitor?

    I have the same monitor and USB works perfectly fine with both an MBA and MBP so I am guessing this could be the place to start troubleshooting.

    no, i didn't even know i had to plug an extra cable. but isn't that cable purpose for printers and similar devices? my macbook only has 3 usb ports, 1 firewire and 1 display port so.. what am i missing?

    Get a cable like this. The one on the left goes into your PC, the one on the right goes into the monitor.

    Display port is just for the video. The USB ports are like any other hub and need to be plugged into your Mac's USB.

    It should have come with that cable.

    Ive just got one of these monitors second hand which runs off my Mac Mini but USB ports arent working. Do I need to connect a USB lead from the Mini to the monitor to enable the USB ports to work? Do I need a cable like the one below?
