Adjusting the USB speed with the Nureva App

The Nureva^® App is a web-based companion app designed to enhance the setup and configuration of HDL310 and HDL410 systems, as well as manage a comprehensive range of audio device settings. A continuous internet connection is not required to use the app.

The app can be accessed over a local area network with a browser and the IP address for the Nureva device. Alternatively, a direct connection to the app is available by connecting an Ethernet cable from the system’s connect module to a tablet, mobile phone or computer.

Using a direct Ethernet connection with the Nureva App

Important

The first time the Nureva App is accessed a browser warning may state: “Your connection to this site is not secure.” This warning appears because the Nureva audio device is protected by a self-signed certificate that is unique to Nureva devices and unknown to the browser. There are two options for proceeding to the Nureva App.

1. Verify that the IP address is correct and select the browser option to proceed to the Nureva App.

2. Connect the computer directly to the Nureva audio device using an Ethernet cable and use the link-local address (169.254.254.254) to proceed to the Nureva App.

Why adjust the USB speed?

USB speeds refer to the data transfer rates of Universal Serial Bus (USB) connections. By default, the HDL310 and HDL410 systems use Hi-Speed (USB 2.0). For some combinations of these Nureva audio systems and third-party devices, matching the USB speeds will provide a better experience. The Nureva App offers the choice of using Full Speed (USB 1.1) and Hi-Speed (USB 2.0) for these integrations.

Matching the USB speeds is sometimes necessary when the accessory or device:

• Uses HdBaseT protocol.

• Is a legacy device that is restricted to Full Speed USB.

• Uses an Enhanced Host Controller Interface (EHCI) host controller.

When to adjust the USB speed

The most common indication that USB speeds do not match is when microphone pickup is recognized but there is no speaker output from the HDL310 or HDL410. This has been reported with these types of third-party products:

• Bring-your-own-device (BYOD) systems

• Bring-your-own-meeting (BYOM) systems

• Room control systems

• Digital signal processors (DSP)

• Android™ computers

• Chrome™ computers

• Older Windows^® and macOS^® computers

• USB over Ethernet devices

Nureva recommends checking the product manufacturer’s user manuals and related documentation to confirm whether the device uses Full Speed or Hi-speed USB connections.

Using the app

The Nureva App can be opened and used on a computer or mobile device that has a supported browser installed. Currently, the Chrome™ and Safari^® browsers are supported.

1. Open a browser and enter the device IP address into the search bar.

2. When prompted for a password, enter the HDL310 or HDL410 enrollment code and click Continue.

3. The app will advance to the Nureva App home page.

4. Open the Inputs/outputs menu.

5. Select USB port.

6. Select the required USB speed.

7. Confirm the setting choice by pressing Restart.

Back to Settings returns the app to the main Nureva App home page.

Troubleshooting

Nureva App does not load

If the Nureva App does not load in the browser, check the following:

• Is the correct IP address being used to access the app?

• Are the computer and the Nureva device on the same LAN? The app will not launch if the Nureva device and computer are on different networks.

• Has the HDL310 or HDL410 system been connected to the internet for at least 6 hours? This will allow the device to complete component updates. Internet access is required only to update the device.
