External Keyboard no longer working with Macbook Pro

[bruceleeroy]

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.

How odd its not showing up at all. I wonder if I can reset the Keyboard or anything.

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
