Kelly,

I recall reading somewhere that the LiDE 400 required USB 3.x ports. And,
when connected to a 3.0 port I could press the 'PDF' button on the front
edge of the scanner, which brought up a simple GUI interface, and was able
to scan a page. So it must accept the USB 3.0 ports when used by itself but
even after adding it to /etc/scan.c/genesis.conf it's not found by
'scanimage -L'.

Did it solve the problem?

I don't know about other Canon scanners but the LiDE 400 has no power
switch. It turns on when the USB cable is inserted.
