Port Trouble: Finding an Elusive Port

If you’re having trouble establishing which port is the one connected to your board, this is for you:

  • Windows: Check out which of your ports you are using by searching for and opening your “Device Manager” in your windows menu. Once there, expand the Ports tab and try disconnecting and reconnecting your USB cable to see which port your computer is recognizing as being plugged in and unplugged.

  • Mac: The Port will look pretty different from Windows! Mine reads as: /dev/cu.usbserial-DMS00S18.

  • To make sure your Mac is noticing the Micro USB, go to  (Apple Logo)-> About This Mac -> More Info... -> System Report…
  • You should then be able to find the USB connection that will look similar to the one below! (You may have to close out of this window and reopen it if you are identifying your USB by unplugging and plugging it back in)
