Supported Canon scanners in Windows 7 64 bit

Question

I realise that the Canon N670U scanner is not supported by Canon, but according to the Canon Website, the LiDe 20 scanner is. Up until now, both scanners used the same driver, so it seems strange that one is supported and the other is not. However, though Canon says new drivers will be on the website for the release of Windows 7, none has appeared yet. Can anyone explain this.
As an aside, I can get the scanner to work using Vuescan, but the cost of buying this utility and being tied to the supplier, compared with simply buying a new scanner is not worth it. It does prove, though that a N670U can work in a Windows 7 64 bit environment.

Answer 1

Peter,   I'm running into the same issue as you.  Have to agree with you, this is a great, reliable scanner.  Unfortunately, it does not look like Canon has any plans to support it in Windows 7 32-bit -- let alone Windows 7 64-bit. The below list of supported products is from Canon's website.
