Reloop RMX-40 USB – when your Mac doesn’t recognise it.

Posted by jpluimers on 2016/02/29

Reloop has posted the below for DJ controlers (like Contour IE, Jockey 3 ME and Digital Jockey 2 ME), but it also applies to their mixers, for instance my Reloop RMX-40 USB – Reloop (but not limited to Reloop audio equipment) in combination with either of my:

  • MacBook Air (13-inch, Mid 2011)
  • MacBook Pro (Retina, 15-inch, Late 2013)

All these machines have USB 3.0 ports. But the workarounds below work:


Some users that own the newest MacBook PRO (2012) with USB 3.0 Ports are reporting problems, that their USB-Controllers are not being recognised. This problem is a known problem with Apple’s drivers and Apple is working on that problem.

Workaround: Use an active USB 2.0 HUB to connect your device.

Two more workarounds:

  • Use a 5 meter bus-powered USB 2.0 Extender with a short (1 meter) USB cable.
  • Use a 10 centimeter bus-powered USB 2.0 4-port hub a short (1 meter) USB cable.

With longer USB cables, you need an external powered USB 2.0 hub.

There is a very crude other solution: replace your Mac drivers with very old ones. I don’t recommend it, but if you want to try: Macbook Pro Retina USB 3.0 Issues FIXED !!! – Xone Forums.
