I am using a Cannon LiDE 35 Scanner with:
Mac OS X 10;8.4, lide35osx7721en, and cstbosx4512ej4
The lide35 driver and cstosx (toolbox) were downloaded today, Sat Aug 21, from:
2. CanoScan Toolbox for OSX (4.512)
5. ScanGear CS (7.721X)
I have only used the 'File' 'button'. Once setting this up from the toolbox window, and scanning once, one is then able to use the 'File' button on the scanner to scan a document into MyPictures folder on my MacBook Pro.
Canon software leaves something to be desired, but for my purposes it is satisfactory.
