Hi I've got a new flatbed scanner, a Canon CanoScan Lide 300. I had a Canon CanoScan Lide 220 before, which worked mostly fine. But then the lamp broke. Both are listed as "completely" supported on the SANE devices page. But that Lide 300 doesn't work.
I'm using Ubuntu 20.04.1 with SANE version 1.0.14-15 (that's the version of the "sane" package). "xsane" says: Failed to open device 'pixma::04A91913': Device busy" "simple-scan" first asks for which scanner to use. It provides a list with one element, which is the correctly recognized CanoScan Lide 300. When trying to scan, this message appears: "Failed to scan. Unable to connect to scanner" "scanimage -L" says: device `pixma:04A91913' is a CANON CanoScan LiDE 300 multi-function peripheral I'm wondering why the Lide 300 is listed as a "multi-function peripheral". It's not multi-function. It's just a flatbed scanner. Maybe those buttons at the scanner are meant (?). "scanimage --device=pixma > image.pnm" says: scanimage: open of device pixma failed: Device busy "lsusb" says: Bus 006 Device 002: ID 1058:25ed Western Digital Technologies, Inc.

For the 220 it's "genesys", for the 300 it's "pixma". I've also found a "driver" from Canon for the Lide 300. But it's *not* a SANE backend, and it doesn't work either. Any idea what's wrong?
