Using A Powered Usb 2.0 Hub; Recommended Usb-Ports - Native Instruments Audio 2 DJ Operation Manual

9.3.3 Using a powered USB 2.0 hub

It is best to connect the AUDIO 2 DJ directly to a USB 2.0 port on your computer. However,
in certain situations a powered USB hub can also be a solution if you are having problems
connecting your AUDIO 2 DJ to an onboard USB port. In this case you should avoid con-
necting other devices to the hub if possible, as each bus-powered device takes its share
from the total amount of power available.
9.3.4 Recommended USB-ports (MacBook Only)
As general rule of thumb, do not use the right hand USB port on a MacBook Pro: this port
is connected to the same root hub as the trackpad. With the AUDIO 2 DJ plugged into the
right port, you can encounter audio problems like clicks or dropouts.
