FAQs

The device is fully compatible with Windows 10. It may be necessary to reinstall the latest drivers after updating from Windows 7/8/8.1 to Windows 10.

You do not need a driver. The driver is already integrated in the operating system.

Turn off your Computer and press at start alt+cmd+p+r until another starting sound appears. With this command the USB bus will be reset and the USB Box will be recognized new.

There are many forum reports about that issue. It is a widely spread error affecting a wide array of USB DACs, unfortunately there is no current fix for this problem, since it lies in the Core Audio of Apple's OSX. We advice not to use our USB DACs with OSX El Capitan.

The DFU needs our driver to be installed as it depends on it. Please first remove the DFU and then install the Windows driver before installing the DFU.
