If your external device isn't recognized by your MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports)

Your Mac might not recognize an external device if it requires more power than your Mac can provide.

If you try to connect an external device to your MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports) and it's not recognized, the device might be trying to use too much power from your Mac and may not be compliant with Thunderbolt 3 (USB-C) power specifications. Mac computers connect to external devices, like external hard drives, that are compliant with the USB specification supported by Thunderbolt 3 (USB-C).

Try using a USB hub, Thunderbolt 3 (USB-C) hub, or power adapter

If your external device needs more power than your Mac can provide, try connecting your device to a powered USB or Thunderbolt 3 (USB-C) hub, or try connecting your external device to its power adapter. Then, connect your hub or external device to your Mac.
