Usb 2.0 Required; Try Another Usb Cable; Usb Troubleshooting - Native Instruments Audio 2 DJ Operation Manual

9.2.2 Mac OS X
In Mac OS X, look into the System Preferences for the Native Instruments USB Audio
Control Panel icon. Open this control panel to see if the device is found. If no device is
found values will appear grayed out. If the Native Instruments USB Audio Control Panel
,
icon is missing here, the driver is probably not installed at all.
►
If the driver is not installed, you can install it using the setup program described in
chapter 4 "Installation."
►
If the driver is not recognized, check your USB 2.0 connection as described in chap-
ter

9.3 "USB Troubleshooting."

9.3 USB Troubleshooting
If you experience problems that may be caused by the USB connection between the AUDIO
2 DJ and your computer, check the following chapters first; several possible sources for
USB issues are covered here.

9.3.1 USB 2.0 required

The AUDIO 2 DJ is an USB 2.0 interface and will not work at all on an 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 meet the
minimum requirements (which were defined in accordance with 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 you might encounter crackles or the device may not work at all.

9.3.2 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 dif-
ficulties; make sure to use a cable bearing the official USB logo.
