Okay, here I am a few years after the initial posts concerning folks having issues with their LiDE 300 scanner. I am haviing identical problems with nothing that is given here being able to resolve it. I also had a LiDE 35 unit that was unusable once I moved to Win7 years back. I liked the unit's operation but could not use it once I moved to Win7 due to driver issues. Now I have issues with my brand new LiDE 300. This is unacceptable for a product like this to be plagued with chronic issues with no resolution. I am packing up this unit and returning it for a refund. Unacceptable product performance.
What model CanoScan do you own?
What version of Windows is installed on your computer?
Is the USB cable connected directly from the scanner to your computer? Or is it connected to a USB hub or docking station?

FYI, I returned the scanner and, due to lack of other choices, bought the next higher model. LiDE 400. That unit performs well on my Win 7 system regardless of anti-virus status. Obviously the LiDE 300 has issues.
I just bought a CanoScan LiDE 300. I'm using Windows 10. I downloaded the latest scanner driver from Canon and installed by carefully following the instrctions. I keep getting the following:
Cannot communicate with scanner for these reasons:
-Scanner is turned off (It is NOT)
-USB cable is disconnected (It is CONNECTED)
Please check and try again
Scanner driver will be closed.
All of these codes are not defined on the Canon support site.
Do I have a faulty unit that needs to be returned?
This error can appear when a security program or firewall setting interfere with the scanner driver from communicating correctly. I recommend contacting Microsoft and have them run a scan of your computer. They should be able to narrow down what could be causing the error.
