Canon N650u scanner not seen in Gutsy

Asked by Bob Dillon

 I have just installed Ubuntu Gutsy Gibbon on my system as a standalone.

According to the docs I have seen thus far, my Canon Canoscan N650u is in fact supported by the latest version of Ubuntu.

In order to edit my files, I did the following:

gksudo nautilus

Went to my /etc/sane.d/dll.conf
# enable the next line if you want to allow access through the network:
# net
plustek

Then went into the plustek.conf file

# Plustek-SANE Backend configuration file
# For use with LM9831/2/3 based USB scanners
#

# each device needs at least two lines:
# - [usb] vendor-ID and product-ID
# - device devicename
# i.e. for Plustek (0x07B3) UT12/16/24 (0x0017)
 [usb] 0x04a9 0x2206
 device /dev/usbscanner

I have also used in the same plustek.conf file the following line:
# For autodetection use
 [usb]
 device /dev/usbscanner

and finally, in the same file

[usb]

I have made the changes and saved them to the file each time, and rebooted the system. I have also unplugged the USB scanner each time and then plugged it back end. Each time, Xsane does not detect the scanner. Is this because I have an older Canoscan scanner?

Thank you in advance!

Bob

according to https://wiki.ubuntu.com/HardwareSupportComponentsScannersCanon?highlight=%28scanner%29 it should work out of the box.

Sometimes there are rights problems. Have you tried to launch xsane as root ?

Yes, I tried the following from terminal:

sudo xsane

Then was prompted whether I really wanted to run this from the /root

Xsane starts, and scans for devices, but no devices are found.

Any other ideas I should try?

I suspect that perhaps one of my drivers, or the /sane.d/dll.conf file needs attention?

Even if I go into the device manager, none of my listings show the Canon USB scanner.

Perhaps something also needs to be addressed in the USB detecting devices as well?

Hi Olivier,

I just tried something I had done before, but hadn't given it much thought:

I went to Terminal, then
lsusb

bdillon@bdillon-desktop:~$ lsusb
Bus 006 Device 004: ID 05e3:0608 Genesys Logic, Inc.
Bus 006 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 005 Device 001: ID 0000:0000
Bus 001 Device 005: ID 046d:c517 Logitech, Inc.
Bus 001 Device 004: ID 04a9:2206 Canon, Inc. CanoScan N650U/N656U
Bus 001 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000

Imagine that!

I had found that when I ran the scanner off the onboard USB, Ubuntu was able to see the scanner without any problems.
I ran Xscan, and Presto!

Xscan works awesome!

Thanks again!

Glad you made it work !

From the link in the ubuntu wiki, you may need to downgrade sane if your scanner do some strange noise.
