This question was asked before on this community but was not answered properly. I'm trying to attach an Apple portable Disk drive to my new Mac Book Pro using a USB to USB-C adaptor. I'm getting the message USB Accessory Needs Power: Connect "Apple USB SuperDrive" to a USB port on this Mac. Impossible to do so directly as the connector from the disk drive is USB. What gives?
MacBook Pro TouchBar and Touch ID, iOS 10.3.2

Good luck & happy trails! 🙂
Or if that wasn't enough there may be other details that were missed.

You didn't say who told you what - or where you were, when you asked.
IF you asked in these Apple support communities, add link back there to
