Adjusting the USB speed with 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.
