title: Is there an alternative to RawInput in Mac OS X/Linux
body: <p>I'm developing an application that runs on a machine that has several usb keyboards attached. Occasionally keyboards will added or removed.  Each time a key is pressed, the application needs to find out which key was pressed, and which keyboard was used.</p>
  
  <p>I have got a working version of the application which uses RawInput under windows.  However windows can take a while to work out whats happened if you add or remove a hub or two full of keyboards, and I'm looking too see if the same can be achieved on a different OS more robustly.</p>
  
  <p>Mac OS X/Cocoa would be the second choice if it is possible, but I am open to suggestions for any other platforms like linux if you can suggest a way to do it.</p>
