It is also useful to test the NI device on another computer. Warning: If you attempt to use another third-party power supply, make sure that it has the same specifications as the NI power supply (output wattage and current), otherwise there is a risk of voiding the device's warranty.

NI Hardware Devices Requiring a 40W Power Supply

TRAKTOR AUDIO 2 (optional, required only for its use with iOS).

NI Hardware Devices Requiring a 18W Power Supply We strongly recommend trying out only another official NI power supply unit ( 18W or 40W depending on your NI device model - see below). Some NI devices require an external power supply for their operation, in which case it is worth trying a different power supply. Although it is common to operate an NI hardware device via a USB 3.0 port as they are found in new generation computers, some systems may pose some connectivity issues with USB 3.0 ports.

Make sure that you are connecting the hardware device to a USB 2.0 port.

This is especially important for hardware devices that do not operate with an external power supply (see next section).

Try connecting the NI hardware via a powered USB hub or directly to your computer.

If possible, try a USB cable that meets the specifications required by NI devices, as explained in this article.

Try out another USB cable, ensuring that the other USB cable is functioning correctly when connecting a different USB device.

To find out whether the problem may relate to the hardware device itself, please perform the following connectivity tests: Verifying the USB Connection Mac OS X 10.10.5 (Yosemite) or later: Verify if an installed plug-in is causing issues recognizing the hardware as explained in this article.

Please consult this article for more information on macOS compatibility.

macOS 10.12 (Sierra) or later: Older NI devices are no longer supported in macOS 10.12 or later and may therefore fail to be recognized.

The NIHardwareAgent or NIHostIntegrationAgent services are not running in the background.
