Completely supported scanner doesn't work

[Volker Wysk]

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.

"xsane" says:
Failed to open device 'pixma::04A91913': Device busy"

"simple-scans" says:
"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.

"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. My Book 25ED

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The Lide 220 and the Lide 300 use different backends. For the 220 it's
"genesys", for the 300 it's "pixma".

Any idea what's wrong?

Regards,
Volker

Hi

I've found a "driver" from Canon for the Lide 300. It's *not* a SANE driver,
SANE isn't mentioned at all in the web pages. Instead they provide a
program, scangearmp2, which you're supposed to use seemingly. But this thing
doesn't work either, even though they say that it supports Lide 300
scanners.

It gives this error message:

"Cannot find available scanners. Cable may be disconnected or scanner my be
turned off. Check the scanner status and then try again."

Bye

Hi

I think scangearmp2 must be launched from terminal. Open a terminal and type scangearmp2 if you have installed this package yet.

Bye

Question: does it work if you run the program as root:

sudo scangearmp2

?

If so, you probably need a udev rule for the device to change ownership and/or
permissions.

Yes, that's what I have done, installed and run it from a terminal.

I've tried it. It's the same.

Hi

I've tried connecting my scanner to my laptop instead of to my desktop. Now
there are *two* devices recognized:

vaio /tmp $ scanimage -L
device `pixma:04A91913' is a CANON CanoScan LiDE 300 multi-function peripheral
device `escl:<a href="http://127.0.0.1:60000'">http://127.0.0.1:60000' is a ESCL LiDE 300 HTTP flatbed scanner

The first one is the same as at my desktop computer. The second one doesn't
work either:

vaio /tmp $ scanimage --device='pixma' > image.pnm
Output format is not set, using pnm as a default.
scanimage: open of device pixma failed: Device busy

vaio /tmp $ scanimage --device=escl > image.pnm
Output format is not set, using pnm as a default.
scanimage: open of device escl failed: Invalid argument

vaio /tmp $ scanimage --device='escl:<a href="http://127.0.0.1:60000'">http://127.0.0.1:60000' > image.pnm
Output format is not set, using pnm as a default.
Capability : [image/jpeg]
Capability : [image/jpeg]
scanimage: rounded value of br-x from 0 to 0
scanimage: rounded value of br-y from 0 to 0
scanimage: sane_start: Invalid argument

Could that be a USB problem?

Puzzled,
Volker

Hi!

Suddenly my old Canoscan Lide 220 works again! On both my laptop and my
desktop... It's crazy!

Cheers,
V.W.

Hi!!

I've found it on the web [1]. The package ippusbxd needs to be removed, then
the CanoScan Lide 300 works.

"For Ubuntu 20.04, this scanner does not work straight forward. The ippusbxd
driver tries to get the USB device, and it locks it."

$ LANG=C apt show ippusbxd
...
Description: Daemon for IPP USB printer support
 ippusbxd is a userland driver for USB devices supporting the IPP USB
 specification. It enables these USB printers to be seen as regular
 network IPP printers.

Bye,
Volker
