    Question Ubuntu server 12.10 - SANE

    Hello guys,

    I have a problem regarding SANE. We have Canon MP500 multifunctional machine and I was able to configure printer corectly using CUPS, but scanner is not working.

    I have installed sane-backends 1.0.23, and many other sane packages (one of them was enormous btw, - 120Mb) but sane-find-scanner doesn't find a thing.
    Still, I can see my scanner using lsusb:
    Code:
    Bus 001 Device 005: ID 04a9:170c Canon, Inc. PIXMA MP500 Scanner
    I am new to linux and I have no idea what do do...

    Canon MP500 scanner access

    I suspect this has to do with "permissions":

    this ubuntu help

    https://help.ubuntu.com/community/Se...nerPermissions

    suggests you edit the file by coping and pasting into a terminal

    sudo gedit /lib/udev/rules.d/40-libsane.rules
    that opens the text editor gedit and then paste into it

    # Canon MP500
    ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="170c", ENV{libsane_matched}="yes"
    ......>>I have edited this from the Ubuntu example that uses a lido scan;

    SAVE CLOSE REBOOT

    .......the good thing you can take from this is linux is fussy about who accesses what......sometimes it bites us all though..

    .....let us know if this advice above is helpful......

    Re: Canon MP500 scanner access

    I appreciate your help, but this line was actually already in the file.

    got anything else?

    Canon MP500 scanner access

    what does

    scanimage -L
    give you ..and if no joy,

    sudo scanimage -L
    .........so you are running this canon MP500 via a usb cable from a standalone computer without a USB hub interfacing........

    my suspicion is that this is all to do with permissions;

    Re: Canon MP500 scanner access

    both commands return the same resault:

    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).

    yep, MP500 is directly conected to ubuntu serverv via USB cable.

    Re: Ubuntu server 12.10 - SANE

    I had exactly the same issue which was driving me nuts,

    sudo scanimage -L

    gave me the scanner

    scanimage -L

    couldn't find it


    this is a permissions problem, I followed all the advice and changed all the settings like you with no luck and the lines for the scanner were already in the file.

    Then all I did was this

    sudo chmod a+w /dev/bus/usb/001/002

    this sorted everything and both commands now work.
    Give it a try and good luck
