I do not have a secondary interface.
The unit is powered via a power supply (plugged in). The USB light on the unit is the only thing not lighting.
That is why I need someone to tell me if that light comes on simply by powering up the unit.
(None of the Focusrite documentation tells me if it should come on when first plugged in - without computer powered up or without the USB cord connected to the computer)
