title: How can I capture the signature of a specific USB device and emulate it in the future?
body: <p>I have software that requires a specific piece of hardware present to be functional. I have the hardware but don't always need it to be connected to use the software. I don't need to emulate the functions of the device, only the fact that it's plugged in.</p>
  
  <p>Is there a way to read how the USB device represents itself and then emulate that signature in software?</p>
  
  <p>I am on Mac OSX 10.7</p>
