Represents a copy of the USB volume.
The USB volume has a range [USB_SPEAKER_VOL_MIN; USB_SPEAKER_VOL_MAX] and must be converted to the volume of the DAC used. We keep back a copy of the last USB volume since Windows ask for the current volume and a double conversion USB -> appli -> USB may lead to imprecision.
