Package: libsane Version: 1.0.19-23 Severity: important Tags: patch I've decided to file a new BR even though I suspect that this will resolve quite a few open bugs both against libsane and scanning frontends.
My HP Scanjet 3300C worked perfectly before, but when I connected it to my notebook today kooka refused to work. It _did_ list the scanner in its initial scanner selection dialog, but in the main window it complained sane was incorrectly installed. The scanner is found: $ scanimage -L device `niash:libusb:005:011' is a Hewlett-Packard ScanJet 3300C flatbed scanner But an actual scan fails: $ scanimage >image.pnm scanimage: open of device niash:libusb:005:011 failed: Device busy Some digging showed: # ls -l /dev/bus/usb/005/011 crw-rw-r-- 1 root root 189, 523 2009-04-09 14:14 /dev/bus/usb/005/011 Even though: # udevadm test /class/usb_device/usbdev5.11 [...] udev_node_add: creating device node '/dev/bus/usb/005/011', major=189, minor=523, mode=0664, uid=0, gid=115 So clearly udev is confused. After all that, the solution! I noticed that the libsane udev rules are completely at the end: [...] 80-drivers.rules 85-pcmcia.rules 90-hal.rules 91-permissions.rules 95-late.rules libmtp7.rules libnjb.rules z60_alsa-utils.rules z60_hdparm.rules z60_libsane-extras.rules z60_libsane.rules z60_virtualbox-ose.rules So, my theory was that the device gets created with default permissons _before_ z60_libsane.rules gets executed. That turned out to be correct. After renaming z60_libsane.rules to 60-libsane.rules, the device got created with the correct group and kooka was happy: # ls -l /dev/bus/usb/005/011 crw-rw-r-- 1 root scanner 189, 523 2009-04-09 14:14 /dev/bus/usb/005/011 It would be great if this could be fixed in a stable update too. Cheers, FJP P.S. Note that udev 0.140 in unstable has again reordered rules and moved them to /lib/udev. I think the rename to 60- will still work though. -- System Information: Debian Release: 5.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.29-rjw (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages libsane depends on: ii adduser 3.110 add and remove users and groups ii libavahi-client3 0.6.23-3lenny1 Avahi client library ii libavahi-common3 0.6.23-3lenny1 Avahi common library ii libc6 2.7-18 GNU C Library: Shared libraries ii libexif12 0.6.16-2.1 library to parse EXIF files ii libgphoto2-2 2.4.1-3 gphoto2 digital camera library ii libgphoto2-port0 2.4.1-3 gphoto2 digital camera port librar ii libieee1284-3 0.2.11-5 cross-platform library for paralle ii libjpeg62 6b-14 The Independent JPEG Group's JPEG ii libsane-extras 1.0.19.11 API library for scanners -- extra ii libtiff4 3.8.2-11 Tag Image File Format (TIFF) libra ii libusb-0.1-4 2:0.1.12-13 userspace USB programming library ii makedev 2.3.1-88 creates device files in /dev ii udev 0.125-7 /dev/ and hotplug management daemo Versions of packages libsane recommends: pn avahi-daemon <none> (no description available) ii sane-utils 1.0.19-23 API library for scanners -- utilit Versions of packages libsane suggests: pn hplip <none> (no description available) pn hpoj <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
