@kdininger is correct.
The only missing piece is that your Monkey version must be current as well (V1.77), that was my problem. Update here.

Update and run the "Line 6 Monkey" app from your computer, NOW you can update your driver.
From there, as kdininger said, try an connect your device. It will say its not reading it. Un-plug it, and plug it in again.
Hope this helps.
