My understanding is that the dB values of this USB device are relative to its maximum gain, and as such consistent in itself. Does the USB spec define the reference level for the dB values?
Not clearly. IIRC, it's against the line level...
The 1.0 spec calls 0 dB line level indeed and (at least in the context of the dynamic range compressor, section 3.5.6.6) suggests that it's "usually 15-20 dB below the maximum level".
