body: <p>I currently need to figure out what is the name of the port that my usb device is connected to. More specifically, <strong>I need to know what to put for the following</strong><a href="https://i.stack.imgur.com/bEi4R.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bEi4R.png" alt="enter image description here" /></a></p>
  <p>I am using a Mac, and I have run the command line <code>system_profiler SPUSBDataType</code>, and it gave me the following. <strong>The device of my interest is the second one:  CP2102 USB to UART Bridge Controller.</strong> But how do I figure out what the serial port that this device is connected to? I need it for my first image.</p>
