Thread: usb printer not recognised (cups)

  1. usb printer not recognised (cups)

    hi all,

    i'm having a problem with my printer, and i have no idea where to look for
    a solution. hopefully someone here can offer a hint.

    machine: ibook G3
    distro: Slackintosh 12.0
    printer: Samsung ML-2510 (USB)

    i have cups installed and running. the usb subsystem works, at least for
    usb sticks and usb hard drives. when i plug in the printer, dmesg and
    /var/log/messages show that it is recognised, and the necessary device
    files are created in /dev and /dev/usb.

    yet, cups cannot find the printer. the cups website says that usb printers
    must be hooked up and switched on before cupsd is started, otherwise they
    won't be recognised. so i restarted cups after plugging in and switching on
    the printer. i even tried rebooting with the printer plugged in an switched
    on. nothing helped, cups just doesn't see that there's a usb printer hooked
    up to the system.

    i used to have slackintosh 11.0 installed on this same ibook, and then the
    printer *was* recognised, and worked. furthermore, i have another laptop, a
    compaq (x86-based, obviously) that runs Zenwalk 4.6, which also recognises
    the printer.

    comparing the output from dmesg or the contents of /var/log/messages on the
    ibook and the compaq revealed that they are virtually identical, nothing to
    suggest a possible problem on the ibook. kernel versions on both machines
    are almost identical, too: 2.6.21.5 on the ibook, 2.6.21.3 on the compaq.

    the only difference between slackintosh 12 and zenwalk/slackintosh 11 that
    i can think of that might be relevant is the fact that slack 12 has hald,
    while zenwalk and slack 11 do not. however, stopping hald has no effect,
    cups still doesn't recognise that there's a printer there.

    anyone here who might have a clue as to what the problem might be, or where
    i could look? i know slackintosh != slackware, but it's close enough...

    I think, this is wrong. I have an HP usb printer, which I switch on only
    when I need it. The only situation when this (sometimes) leads to a problem
    is when I switch on the printer _after_ I send a file to it.

    I don't have hald running either.

    Sorry, I don't have a clue. The only thing I can recall is that I
    couldn't make the printer work until I installed ap/hpijs in Slack-11
    and ap/hplip in Slack-12.

    Looks like some people were having trouble with udev when upgrading to
    current.

    what i meant to say was that the cups documentation states that when you
    configure a usb printer, it needs to be plugged in and switched on before
    starting the cups daemon. once it's configured, it is indeed not a problem
    anymore.

    hplip is already installed. i reinstalled it, just to be sure, but to no
    avail.

    i compiled cups 1.3.3, and tried with that, but no go.

    i think i'll try a cups mailing list, hopefully the cups experts have an
    idea...

    this is a clean install of slackintosh 12, so there shouldn't be any
    upgrade problem with udev...

    hey, thanks! that looks like it could be relevant. the printer does indeed
    not show up with lsusb.

    i just downloaded 2.6.23rc9. i'll try and compile it tonight, see if it
    works...

    it works! compiled the new kernel, installed it, rebooted (repeat three
    times due to a bug in yaboot...) plugged in the printer, and now lsusb
    shows it! configured cups and now i'm printing again!

    thanks, ken, for pointing me to that page!

    It's simple posts like these that demonstrate just why this is among
    the most knowledgable newsgroups in all of USENET. Kudos to you, Ken,
    and have a BOZO point on me. I couldn't for the life of me figure that
    one out.

    yes. unfortunately, the upgrade to the latest kernel caused a problem with
    resuming from suspend-to-ram. for some reason, the system time isn't reset
    anymore after a resume, so that i have to run hwclock -s by hand to get the
    time right... :-/

    but hey, at least my printer is working. ;-)

    Thanks Alan, you had better keep the point as it was more luck than
    skill that I came up with that answer. :-)
