Humm... The point is: the interface (Behring) has RCA output, which is
connected to the LineIn of the integrated sound card (not an USB
card). On the other hand, it also has a USB output, which is used to
get Phantom Power (whatever that is), which works (when removed from
the USB entry in the computer, the LEDs go off). However: I think the
device (Behring) also works as a USB sound card (which I don'y want to
use).

So it seems that it is recognized as a USB sound card...

No buttons in the Mic; there is a button in the interface that enables
the Phantom Power, but it has always been on.
