I got it working. You have to force it use the LiDE 60 driver by choosing 'Have Disk' / 'Select from a list' It's been working perfectly for two weeks with no instability. I can't understand why Canon doesn't have an official driver since it's obviously very similar to the LiDE 60. Thanks for this! I went to Control Panel > System > Device Manager The scanner was with a '!' under "Other devices" Properties and Driver update.... and as you guys said, force it to use the LiDE 60 driver.
