    Color Scanning via Brother ADS 2200 and 2700 (brscanads2200ads2700w)
    
    The name for the color mode is slightly different for the brscanads2200ads2700w backend. Without this the 
scanner only scans in black and white. I tested it locally with a Brother ADS-2700w over USB and it allowed 
me to scan in color like XSane.
