Hi,
I am currently using a Pioneer DDJ-SX controller and connecting to my Macbook Air (2014) using Rekordbox which I newly purchased. I have been using the controller with the laptop for a while now and have had no problems, but recently the controller has stopped appearing when I connect the two.

Using the FAQ page on your website I have looked for solutions and none have worked so I think there must be a fault with my controller. Have tried different cables, different laptops still nothing helps. An hour ago the controller popped up briefly, giving me more belief that the USB port is broken.

Any help would be greatly appreciated.

Many thanks,
Dom.
