If scanning with USM on or off affects your RGB image then you're really
not scanning in RGB.
Some high end CMYK Drum scanners offer RGB scanning but it's really just
a conversion to RGB after the CMYK image is made.
Our DS scanner does this.
Since USM is only applicable in CMYK, this is a tipoff that you're
scanning cmyk and having it converted to rgb.
