Recommended Solution

SCU displays the following error message even when a virtual USB device is mapped or when a physical USB device is connected:

No USB Disk on Key detected

  • For USB devices that are mapped through Vmedia, use the USB reset option from the Vmedia user interface. (Virtual Media Session > Details > USB Reset)

  • For USB devices that are physically connected, check the vendor or product information. Try connecting a different USB device.

After installing a Microsoft Windows operating system using UCS SCU, the Windows Device Manager shows some devices with a yellow bang.
