title: How to get the UUID of a USB device on a Mac?
body: <p>I'm currently facing a problem where an OS application is not showing one of two devices because according to the console logs, these devices have the same UUID. The devices have different vendor IDs, different product IDs, vendor name and device name. Out of the billions of possible UUID combinations, they had to clash.</p>
  
  <p>How does the OS compute the UUID of a USB device?
  What USB info is it based on?</p>
  
  <p>Additional info:
  Their serial numbers are the same, which are both currently zero. Is UUID just based on the serial number?</p>
