[sane-devel] Canon Canoscan LiDE 400 support in Slackware

[Rolf Bensch]

Hi,

My LiDE 400 is working with recent SANE version 1.0.30-914-g8bdd27d14.
You need at lease SANE version 1.0.28.

Please check your installed SANE version with 'scanimage -V'.

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.

Hopr this helps.

Cheers,
Rolf
