    Hey guys,
    I have a Cinema display and Apple External keyboard that I connect to my macbook pro. The External Keyboard used to work perfectly until I connected it to a pc and then tried to reconnect it to the Macbook. Now it won't work at all. What should I do? Restarting and plugging it into the other usb ports doesn't work.

    Is there any way to see if the Macbook Pro detects the Keyboard at all? I just tried plugging it back into the PC and it works perfectly.

    system profiler will show what usb devices are plugged in / recognised.

    Microsoft Natural Keyboard not recognized

    I have a similar issue. I had connected my Microsoft Natural Keyboard to my MacBook Pro before and it worked. Now, actually the first time ever after I upgraded to Lion, my mac won't recognize the keyboard and the connected mouse also behaves strange as soon as I connect the keyboard.
    Any ideas?

    Thanks, René
