AUDIO KONTROL 1 – 103
8.2.1. USB 2.0 required
The AUDIO KONTROL 1 is a USB 2.0 interface and will not work at all on a USB
1.0/1.1 port.
In addition, although the minimum power specified for a USB 2.0 port is 500 mA,
we have seen a few cases where the USB 2.0 ports on certain computers do not
fulfill the minimum requirements and therefore do not meet the official USB 2.0
specification. In this case you may see a message saying that there is not enough
power available to operate your device.
In this case the Controller might produce crackles or might not even work at all.
8.2.2. Try another USB cable
A bad USB cable can be responsible for audio dropouts and other connectivity
problems. It is highly recommended that you try using a different cable if you are
experiencing difficulties; make sure to use a cable bearing the official USB logo.
8.2.3. Using a powered USB 2.0 hub
It is best to connect the AUDIO KONTROL 1 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 KONTROL 1 to an onboard USB
port. In this case you should avoid connecting other devices to the hub if you can
as they will take diminish the total amount of power available.
8.2.4. Disable USB energy saving mode
If you’re having problems with AUDIO KONTROL 1 crashing or performing badly
on a Windows® machine, the first thing to do is to disable power management to
the USB hubs. XP turns this on by default. Go to device manager (Control Panel/
system/hardware) and right click a USB hub to bring up properties. On the power
management page, uncheck all boxes. Repeat for each hub and reboot.
