Canon LiDE20 not workingPosted: February 29, 2016
So you have a new computer with those blue USB3 ports and are using probably Linux Mint 17.3 Mate, Ubuntu 14.04 or similar OS.
The Canon LiDE20 scanner which used to work with your older computer, refuses to scan now.
If you enter “scanimage -L”, you get output shown here below, followed by a long wait:
- device `plustek:libusb:002:003′ is a Canon CanoScan N670U/N676U/LiDE20 flatbed scanner
The problem is related to the fact that your system has USB3 ports.
One way to solve the problem is to go to BIOS setup of your computer and look for USB ports related options.
With my ASUS motherboard I fixed it like this:
- F2 or Del at boot for BIOS setup
- Advanced Mode (F7)
- USB Configuration:
- Intel xHCI Mode -> change from Smart Auto to Disabled
