Black USB 3.0 Female to Dual USB Male Extra Power Data Y Extension Cable for 2.5" Mobile Hard Disk CableCC

That cable works, the 2.5” drive in an enclosure I brought to my mom’s for the Wii U, powers up now. As soon as I turned the Wii U on, it said there was a hard drive that needed formatting.

You can get that cable for $6 on Amazon.
