Hi Rolf, This scanner has problems working via USB hosts. You need to connect it directly to your computer. And I can scan via USB3. But it's not faster than USB2. It's still connected as USB2 device. AFAIR, this scanner is powered from USB, which implies particular requirements on amount of

Hi, The LiDE 400 is fully supported by the pixma backend (see: http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA). You need to install recent SANE version 1.0.28 from git snapshots (http://www.sane-project.org/snapshots/). Hope this helps. Cheers, Rolf Am 11.01.20 um 15:20
