    That works fine on mine. Perhaps the problem is your hub. Is it a hub designed for direct connection to USB-C or must you use a USB A to USB C adapter? If the latter then it may be a faulty adapter. Is the drive self-powered or bus powered? If the latter then maybe the drive draws too much power to work. Or you may need a hub that can pass through power from the AC adapter to the computer. HooToo makes a good 3-port hub you can buy on Amazon with power pass-through.

    Please update your Macbook 12 now! Apple just released a new OS X El-Capitan 10.11.5 update and it works like charm again!
