Korg nanokontrol problem - USB cable issue

The Korg NanoKontrol midi controller used for live recordings did not work at all despite many attempts at disconnecting and re-connecting. Had to use the mouse and trackpad. Some tips:

• Hovering over a track and using the scrollwheel of the mouse will move the corresponding fader. Rotating the wheel slowly makes small changes, rotating the wheel fast makes large changes.
• Clicking on a point on a fader causes the fader position to move to that point.
• Multi-touch on the trackpad - two-finger slide is similar to rotating scrollwheel.
  

Tried out another USB cable - thankfully that made it work.
