i have just had some minutes to recompile libsane-hpaio from Quantal's current source package (3.12.6-3ubuntu4) after applying the patch provided by Sanjay Kumar in comment #8 above and i can confirm that Sanjay's patch fixes the issue for me.
Peter, i'm not sure why installing hplip-3.12.10a from source or from hplip's upstream packages is not fixing the issue for you - as far as i can see from hplip-3.12.10a source tarball, the patch i have applied manually to the Ubuntu 3.12.6-3ubuntu4 package is there in upstream's latest release. having said that, i *think* that before coming to identify the Ubuntu Q libsane-hpaio as the cuprit for the issue i was experiencing, i had indeed tried installing a newer version of hplip from upstream and that did not fix the issue for me either. now i can't remember if that was 3.120.10 or 3.12.10a, although i *think* it was the former - but this specific bit of code was added in 3.12.9 so that's pretty weird. maybe i had inadvertently left around some Ubuntu library before installing hplip upstream. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1069898 Title: regression: cannot open network scanner with error "unable to read device-id ret=-1" Status in HP Linux Imaging and Printing: Fix Released Status in “hplip” package in Ubuntu: Confirmed Bug description: under Ubuntu 12.04 i could scan perfectly via the network from my HP Photosmart Premium MFP (HP C309A), using gscan2pdf as frontend. during Quantal beta and now on Quantal release, i cannot access the network-connected scanner anymore: when opening the scan dialog in gscan2pdf, the error message displayed is "Error opening device: End of file reached". on closer inspection, and having tried all the different backends available in gscan2pdf, this seems related to the package libsane- hpaio: if i downgrade this single package to libsane- hpaio_3.12.2-1ubuntu3.1_amd64 from Precise i can scan ok (only side effect is that gscan2pdf hangs on exit and needs to be killed with signal SIGKILL). in syslog, these are the lines that appear when using the newer libsane-hpaio from Quantal when a frontend application tries to access the scanner: perl: io/hpmud/pp.c 627: unable to read device-id ret=-1 perl: io/hpmud/hpmud.c 611: invalid channel_open state perl: failed to open scan channel: scan/sane/hpaio.c 659 perl: sane_hpaio_cancel: already cancelled! perl: io/hpmud/hpmud.c 611: invalid channel_open state perl: failed to open scan channel: scan/sane/hpaio.c 659 perl: sane_hpaio_cancel: already cancelled! perl: io/hpmud/pp.c 627: unable to read device-id ret=-1 hp-check completes without errors nor warnings and correctly finds the network-connected scanner: ------------------------------ | DISCOVERED SCANNER DEVICES | ------------------------------ device `hpaio:/net/Photosmart_C309a_series?ip=192.168.2.10' is a Hewlett-Packard Photosmart_C309a_series all-in-one hp-scan displays a similar error message to gscan2pdf: $ hp-scan -d hpaio:/net/Photosmart_C309a_series?ip=192.168.2.10 -s viewer HP Linux Imaging and Printing System (ver. 3.12.6) Scan Utility ver. 2.2 Copyright (c) 2001-14 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY.
