What does this warning on a MacBook Pro mean: “USB Device Needs Power”

Super User Asked by BillC on December 30, 2020

I just reconnected my MacBook Pro to all of its normal devices for “desktop” type operation. Now I’m getting a warning: USB Device Needs Power – Connect “Internal Memory Card Reader” to a USB port on this Mac. What does that mean?

One Answer

You probably have the Memory Card Reader connected to a USB port on another device that is connected to the MacBook. The warning is telling you to connect that card reader directly to a USB port on your MacBook rather than indirectly via another device.
