It used to work (even though not officially supported). I wouldn't be surprised if the feature was removed recently. There's just too many problems associated with USB printing. Anyway you could try an older version of Cura but I recommend printrun/pronterface (it's free). Or octoprint on a rasberry pi and you now have a network printer.

Printing over USB is not a supported option for the Ultimaker². I'm not sure if Cura deliberately prevents you from trying to do it... if you really want to, you try using Pronterface or another printer control program to submit the gcode. However, you'll need to make sure that you have Cura set up to make regular Marlin gcode, not Ultigcode - as the latter makes assumptions that are only honored when printing from SD card.
And printing over USB is slower and less reliable than working from the SD card, so I recommend that you just use the SD card.
