You fall into the same category I do with my LiDE 220. It somehow just doesn't like USB 3.x ports. I think we were working on the issue still. Olaf can remind me (as it's early and coffee is just being had here).
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'.
As a work-around, I ended up putting this in my PC: https://smile.amazon.com/gp/product/B002RL8V7E/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
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. Regards, Rich
