Using A Powered Usb 2.0 Hub; Recommended Usb-Ports (Macbook Only); Disable Usb Energy Saving Mode (Windows Only); Update The Driver - Native Instruments Komplete Audio 6 Instruction Manual

8.3.3 Using a powered USB 2.0 hub
Connect the KOMPLETE AUDIO 6 to a USB 2.0 port directly on your computer. In certain
situations, a powered USB hub may also work (e.g., if you are having problems connecting
your KOMPLETE AUDIO 6 to an onboard USB port); in this case, try to avoid connecting
other devices to the hub if possible, as each bus-powered device takes its share from the
total amount of power available per bus.

ther instructions.

8.4 How to avoid Ground Loops
Ground loops are a common problem within any environment where multiple electrical de-
vices are connected to the same power circuit. In complex setups, the cause(s) of the noise
can be difficult to find. Ground loops are perceived usually as a hum or buzz in your audio
signal, but this can also transmit and amplify other sounds from the devices connected to
the circuit. For example, one very common problem is that you hear internal clicking sounds
created by your computer.
The cause of the noise is usually the computer and its internal devices, or devices connected
to the computer such as external hard drives (note that even if the power supply of your
notebook computer is not connected, your setup may still be vulnerable to ground noise from
an external device with its own power supply). The cause can also be any other device (such
as a radio or television). The reason why this noise is present at the monitor speakers input
has to do with a loop in the setup of your electrical and audio cable connections. Most likely
this loop occurs through the ground of one or more of these cables. With this in mind, the
following section should help to eliminate the ground loop.
