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

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 power that USB port can give away, may be 
somehow above standards.

USB 3.0 ports can give more power, which may make them more reliable 
with this device.
