Thanks,

QUICK ANSWER: use the original USB cable that came with the scanner.

LONG EXPLANATION:
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(?).

You can find all drivers, software, and manuals HERE.

I would uninstall what's on the PC for the scanner first, reboot. then start again. Leave the USB cable unplugged untill the software is installed.

Hope that fixes Ya...

This works for 32-bit, maybe try the same for 64 and see if it works?
1) Download the drivers for XP from Canon's website
2) Install the drivers.
3) They will install to C:/Temp/CanoScanCSUv571a, go there
4) There is a compressed file called: CanoScanCSUv571a.exe in the foler
5) Use 7-zip to uncompress the folder
6) Plug in your scanner
7) Go to your device manager under the Control Panel
8) Go to Imaging Devices and select your scanner
9) Right click to update driver information
10) Select browse my computer for driver software
11) Type in: C:\Temp\CanoScanCSUv571a

Downloading software (Twain??)


The download website for your scanner is here:

http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=351&modelid=8008

A TWAIN driver is simply a generic scanner software driver that your specific Canon software can hook into and use.

I recommend starting with this one and see if it installs the TWAIN driver you need:

"CanoScan Toolbox v2.2.3 for Windows 98/Me/2000/XP"
