A:AnswerHello Irishwabbit,
I understand you will like to know what the micro USB port in the back of your Echo Show 5 (2nd Gen) with Alexa is used for. The micro-USB port can be used with an micro-USB-to-Ethernet adapter to facilitate a wired network connection. Hope this has answered your concern, have a nice day.
A:AnswerHello, Brian!
The Echo Show 5 does not have a built-in Zigbee hub. The Echo devices that do have a built-in Zigbee hub are the Echo Show 10, Echo Studio, Echo Plus, and Echo (3rd Gen). I hope this information helps. Have a wonderful day.
