What needs to be understood is the ASUS STRIX RAID DLX PCIe card  partially acts as a USB 3.1 adapter to the ASUS XONAR SC200 sound device that is built on the same circuit board so because of this there may be a need to install the Asmedia PCIe to USB Drivers first. The Asmedia drivers are below the sound device drivers. Refer to ASUS for more information they still support the product.
