title: CP2102 device is not listed in /dev on macOS 10.13
body: <p>I have the ESP32 board with Silicon Labs CP2102 controller. When I connect it to my MacBook, I can get the details about this device using the command <code>system_profiler SPUSBDataType</code>, but it is not listed in <code>/dev</code> as a virtual serial port - so I can't communicate with it.</p>
  
  <pre><code>    CP2102 USB to UART Bridge Controller:

  <p>I'm using the official driver downloaded from <a href="https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers" rel="noreferrer">https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers</a>.</p>
  
  <p>Any ideas how to make it visible in <code>/dev</code>? I have also Windows installed on the same computer where it works fine, so the HW and the USB cable are OK.</p>
