Windows 10
Under Bluetooth and other devices
I accidentally removed device called "Unknown Device- Audio"
.. Fireface 800 stopped working

I tried turning Fireface off and back on, Unknown device came back with no "audio"
FF doesn't show up.

Tried re-installing drivers (latest), says "ready to use" but when I turn on FF, Device manager just shows "Unknown device" No FF .

Tried right clicking "Unkown Device" and updating driver selecting FF driver but says "Windows found drivers for your device but encountered an error while attempting to install them" "one of the installers cannot perform installation at this time"

Been using this interface for decades with no problems.  Just clicked one thing by mistake!

Please help, Time is of the essence,
Thanks
