[sane-devel] "scanimage: sane_start: Invalid argument" with a Canon LiDE 220 scanner

[YuGiOhJCJ]

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
---

Do you know how to fix that please?

Thank you.
Best regards.
