Canoscan LIDE300 scanner on Buster

#1 Post by kskruser »

Hi all...

Has anyone succeeded in getting the Canon "Canoscan LIDE300" scanner to work under SANE on Buster?

Yes, I know, I have the 'ScangearMP2' scanner program from Canon - it works OK, but is very limited - low resolution, no general settings at all. Surely we can do better...

Here's the output of 'lsusb:

Code: Select all

Bus 005 Device 003: ID 04a9:1913 Canon, Inc. 
Bus 005 Device 002: ID 03f0:b511 HP, Inc 
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 002: ID 0480:a202 Toshiba America Inc Canvio Basics HDD
Bus 007 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 006 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Note the very first device. The USB system 'sees' my scanner.

Here's the (partial) output from 'sane-find-scanner':

Code: Select all

Again note 1st line - SANE also seems to 'see' the device.

However, 'scanimage -L' gives me this

Code: Select all

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
So, no scanner. I'm powerful confused!

Any suggestions?

There was a problem with usb3 ports in the past. I had a similar problem with my lide 250 scanner.

The workaround that worked for me was:
"SANE_USB_WORKAROUND
If your scanner does not work when plugged into a USB3 port, try
setting the environment variable SANE_USB_WORKAROUND to 1. This
may work around issues which happen with particular kernel ver-
sions. Example: export SANE_USB_WORKAROUND=1."
