title: Eject USB Device (no disk) on MAC osx
body: <p>I want to access an usb device from my nodejs application. Unfortunately it seems like my MAC already claimed the usb device, which leads to failures in the library I use. </p>
  
  <p>I can see the usb device with <code>system_profiler SPUSBDataType</code>. The device is a coin acceptor so <strong>it is not a disk, thus not removable with <code>diskutil</code></strong>.</p>
