The device is fully compatible with Windows 10. After an update from Windows 7/8/8.1 it might be necessary to reinstall the driver.
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.
Please uprade the firmware of your unit to minimum version 1.04 (in Downloads). After that your DAC Box DS2 ultra should work normal.
The DFU depends on our driver. Please remove the DFU and then install the driver before reinstalling the DFU.
