I have 2 Edisons and both of them are 100% fine at scanning ALL the barcodes EXCEPT for the line-tracker.

When running the line tracking program please make sure you start Edison's line tracker on the white reflective surface.
When Edison is started the line tracker takes a reading and calls that a "reflective" surface, Edison then looks for a sharp drop in reflected light and calls that a "Non-reflective" surface. If Edison starts on the black line, Edison will never see a sharp drop in reflected light and will spin in circles
