    Scanner on ltsp 8.04

    Hello
    (Sorry for mistakes, I'm not English)

    I installed ubuntu 8.04 in ltsp mode, all work fine.

    I try to detect a usb scanner, it works on the server (i can scan from xscane) but it doesn't work from clients (the scanner it doesn't see as a scanner).

    I do this :
    - I edit /opt/ltsp/i386/etc/lts.conf
    Code:
    [default]
    XINETD_SERVICES = "saned"
    LOCALDEV=True
    - I put the privilege for my user
    Code:
    jack@srv-ltsp:~$ id
    uid=1000(jack) gid=1000(jack) groupes=4(adm),20(dialout),24(cdrom),25(floppy),29(audio),30(dip),44(video),46(plugdev),105(scanner),107(fuse),109(lpadmin),115(admin),1000(arno)
    I rebuild the ltsp image and restart my clients
    Code:
    /opt/ltsp/i386/etc/lts.conf
    But when I plug the scanner on my clients, xsane says that It does't find peripheral
    dmesg from the client in graphic (I think it's the scanner??)
    Code:
    [145773.415815] usb 6-3: reset high speed USB device using ehci_hcd and address 2
    [148326.084096] usb 6-3: reset high speed USB device using ehci_hcd and address 2
    when i do "scanimage -L" and "sane-find-scanner", it returns that it doesn't find any peripheral

    I forgot something???

    Thanks
    Jack

    I created a similar post, but for Ubuntu 8.10. No solution yet:

    Take a look here - http://www.k12ltsp.org/mediawiki/index.php/Scanners
    This information looks like what you need.

    Hi dejuren,

    Thanks for the post.

    I checked your link but it didn't help me. I actually did not even try it, because there is no sane.d directory in /opt/ltsp/i386/etc/ . So except for assigning static address to client I wouldn't be able to do anything else from that instructions. And I decided not to try them.

    Today I figured it out with the help of a friend.

    I checked ownership and group of scanner and it was:
    Code:
    ls -l /dev/bus/usb/001
    total 0
    crw-rw-r--  1 root root 189,  0 2009-01-29 21:54 001
    crw-rw-r-+ 1 root root 189, 22 2009-02-01 13:59 023
    023 is the scanner

    I identified two combinations as a solution:
    A. Change group to Scanner, or
    B. Change permissions for Others to Read and Write

    I think A. is the best.

    I noticed that this solution is only temporary. After a restart the permissions are set to root again. I guess it is the way it should be.

    I will be grateful if someone provides a permanent solution. Thank you.
