This troubleshooting guide helps you resolve issues related to your NI hardware not being recognized on your Windows system. The symptoms include the following:
- The LEDs on the hardware do not light up / do not flash when connecting it to the USB port.
- The USB LED on the connected device is blinking.
- Audio interfaces only: The device is not available from the list of device drivers in the audio settings of your audio application or Windows operating system.
This article is divided in the following chapters:
- Troubleshooting the hardware device
- Troubleshooting the device driver and firmware
- Verifying the hardware status
To find out whether the problem may relate to the hardware device itself, please perform the following connectivity tests:
Verifying the USB Connection
- Try out another USB cable, ensuring that the other USB cable is functioning correctly when connecting a different USB device. If possible, try a USB cable that meets the specifications required by NI devices, as explained in this article.
- Try connecting the device via a powered USB hub. This is especially important for devices that do not operate with external power supply (see next section).
- Make sure that you are connecting the sound card to a USB 2.0 port. Although it is common to operate an NI audio interface 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.
Verifying the External Power Supply
Some NI devices require an external power supply for their operation, in which case it is worth trying a different power supply. We strongly recommend to try out only another official NI power supply unit (18W or 40W depending on your NI device model model - see below).
NI Hardware Devices Requiring a 18W Power Supply
- MASCHINE STUDIO
- KOMPLETE KONTROL S88 / S61 / S49 / S25
- TRAKTOR KONTROL S5 / S4 (MK1 & MK2) / S2 (MK1 & MK2)
- TRAKTOR AUDIO 2 (optional, required only for its use with iOS)
- TRAKTOR KONTROL Z1 (optional, required only for its use with iOS)
- TRAKTOR AUDIO 6 (optional)
- TRAKTOR AUDIO 10 (optional if the latest firmware has been installed)
NI Hardware Devices Requiring a 40W Power Supply
- TRAKTOR KONTROL S8
- TRAKTOR KONTROL D2
- TRAKTOR KONTROL S4 MK3
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 losing the device's warranty.
Test the Device on a Different Computer
It is also useful to test the NI device on another computer. Make sure that the second computer is meeting the product's system specifications and that the device's driver has been installed. If the device fails to light up on the second computer, the hardware could be defective. In this case, please contact our hardware support team.
If the driver and / or firmware of your NI device has not been correctly installed or is not up-to-date, your device may not be recognized and the light(s) on the device will blink upon connecting it to your system. Follow the steps below in order to ensure that you have installed the driver / firmware correctly:
Class-compliant WASAPI Drivers (Windows 10)
New NI devices make use of the WASAPI Exclusive technology and do not require a driver installation. These 'class-compliant' drivers can only be used on Windows 10 or higher. Read this article for more information.
In order to ensure that the WASAPI drivers are working, please install the latest Windows updates as explained below:
- Click on the Start button at the bottom left corner of your Desktop.
- Type Check For Updates and click on the top result.
- Go through all available updates by clicking the Check for updates button.
- Repeat steps 1 through 3 until all updates are installed.
Most NI devices require the installation of an ASIO driver on Windows.
Go to our Drivers & Other Files page and download the latest driver version for your operating system. In the below example we are downloading Traktor Kontrol S4 Driver 3.1.0 - Windows 7 and above.
A firmware is a specific type of software which is directly installed on your hardware device. There are firmware updates available for many NI hardware products. If the firmware version of your device is not up-to-date, your device may not be recognized or you may experience performance issues. Read this article to make sure the latest firmware is installed on your device.
Verify the hardware status of your device in order to determine if it is being correctly recognized by your Windows system:
- Make sure your NI device is connected to your computer's USB port.
- Open the Start menu and type 'devmgmt.msc' in the search bar, then hit the Enter key to open the Windows Device Manager.
- Expand the entries Sound, video and game controllers and Universal Serial Bus devices. If an exclamation mark appears next to your device entry (see picture), install the driver manually as explained below:
- Right-click on the device entry and select Update Driver Software... from the menu that appears.
- In the window that opens, choose Browse my computer for driver software.
- Browse to the following directory: C: > Program Files > Native Instruments > *Device Name* Driver > Inf
- Click OK to load the driver.
