I am wondering. According to 
http://www.sane-project.org/unsupported/canon-lide-70.html I found that 
the output of sane-find-scanner didn't identify this scanner as GL841 
based. How did you find this?

Canon LiDE 600F has only 2 endpoints.
Canon LiDE 70 has also only 2 endpoints.

So I wanted to read a usb log to check if the protocol is the same.

Canon LiDE 35 uses 3 endpoints. So it's different.

Your log shows many URB_FUNCTION_VENDOR_DEVICE lines.
Canon LiDE 600F doesn't use any vendor device function.
As far as I know...
This means I can't find any in my log.

Canon LiDE 35 has definitely not the same protocol.

If you want to check yourself my logs, have a look at

Microsoft is not the answer. Microsoft is the question.
"NO" is the answer.
