Hello,
I confirm that the workaround on your link is working.
If I set "SANE_DEBUG_SANEI_USB" to "5" then I am able to scan.
I confirm that it works.
However, I don't understand how a debug variable can fix the problem.
Is there a better way to fix that please?
Thank you.
Best regards.

Hello,
I own a Canon LiDE 220 scanner.
This scanner is working perfectly fine on Windows 8.1 (64-bit) so I
suppose that it is not broken.
Here is what happens when I try to use it with SANE on Slackware 14.2
(64-bit):
---
$ scanimage --version
scanimage (sane-backends) 1.0.32; backend version 1.0.32
$ scanimage -L
device `genesys:libusb:001:004' is a Canon LiDE 220 flatbed scanner
$ scanimage >image.pnm
Output format is not set, using pnm as a default.
scanimage: sane_start: Invalid argument

Sounds like this is more than an isolated incident:
