QUICK ANSWER: use the original USB cable that came with the scanner.
Using Vista (32 bit version) and a Canon N670U scanner with the new drivers installed from the CanonUSA website. This driver is works for Canon scanners: LiDE 20, LiDE 30, N670U, N676U and N1240U, found at http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=235&modelid=6625
Canon says it doesn't support Vista 64 bit version. I couldn't get the scanner to work and kept getting the TWAIN error also, despite uninstalling / reinstalling the driver. Finally, decided to disconnect my 3rd party 16 foot USB cable and use the original cable. I swear, it WORKED! I can't explain why, but it did. Perhaps there is increased resistance, hence reduced power going to the scanner by using longer/different USB cable? Anyhow, it worked...go figure. If you have the 64 bit version of Vista, I guess it won't work(?).

Try using the original USB cable that came with the scanner. I swear it worked for me, even though it doesn't make sense (although I suppose there is increased resistance, thus less power going to the scanner by using a longer and/or different USB cable than the one included). Give it a try.

Well I had a code 15 error with mine LIDE 20. Apparently the scanner needs a certain amount of power to run off the USB port. So I changed the USB port and problem fixed
