Question about Canon CanoScan 9900F Flatbed Scanner
Can't get my Mac to recognize my Canoscan 9900F via Photoshop CS3 or Canoscan utilities
You could try looking in system profiler, to see if the scanner is even recognised by the system - if not it's a connection problem.
try connecting via firewire instead of USB (or vice versa)
otherwise, see if vuescan recognises the scanner.

Tips for a great answer:
Guide to installing Canon CanoScan LiDE 35, 50 and 60 on Mac OS X 10.8. Mountain Lion:
FIRST PART: DELETING OLD LiDE DRIVERS AND SOFTWARE
HD:/Library/Image Capture/Twain Data Sources
delete the CanoScan CanoScan XXXX.ds file
(Make note of any other files that may be in this folder. If other files are present, move them to the desktop for now. Then place them back after successfully using the scanner.)
delete the 'CanoScan XXXX' folder
delete the folders containing the name CanoScan, or starting with CNQL.
delete the CanoScan Toolbox Application
delete any items named "CanoScan Toolbox"
SECOND PART: MAKING YOUR SCANNER WORK
CanoScan LiDE 50 and LiDE 35 work both with the 35 driver:
CanoScan LiDE 60 driver:
VueScan 9.2 (or later) x32 for Mac OS X
Alternative to VueScan: CanoScan Toolbox. I prefer VueScan.
Try your luck with Version 4 or Version 5.
CanoScan Toolbox 4: cstbosx4934ej4.dmg
CanoScan Toolbox 5: cstbosx5014ej4.dmg
(Alternatively try and install CanoScan Toolbox 4 or 5)
