Bug 201028 – media-libs/libgphoto2-2.4.0-r1 installs buggy udev rules and breaks usb-printer/cups

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tiziano Müller (RETIRED) 2007-12-02 21:49:20 UTC]

It seems like a variation of this bug here: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/76077
... but in our case it's caused by line 11 (see below) which sets the group for all usb devices to plugdev. This also overwrites GROUP="lp" for usb printers which results in cups not being able to detect or print to usb printers.

Hi all,
I have exactly the same problem here. I'll try to temporary put 'lp' user in the 'plugdev' group so cups can access the printer, but it doesn't work.

If someone has a quick fix, I'll be happy.

Thanks

I just had a look at the ubuntu bug. I'll take a look at their patch and forward it upstream if necessary in the coming days (probably tomorrow).

[Comment 3 Tiziano Müller (RETIRED) 2007-12-04 18:14:03 UTC]

@David: Please don't do that. As a workaround you can comment out the line 'GROUP="plugdev"' in /etc/udev/rules.d/70-libgphoto2.rules and reload the udev-rules by either restarting or doing 'udevcontrol --reload_rules'

@Gilles: It's not the same problem, but a similar one. We don't have the match for all vendor-id's, but the buggy 'GROUP="plugdev"' line instead, as written above.

looks like the issue is resolved in 2.4.1. Please reopen if it's not the case.

[Comment 7 Aron 2008-03-30 22:57:06 UTC]

Yep, this is fixed.  It also fixed the problem with my Olympus camera not being recognized as a mass storage device. :-)

Hi
This problem is not solved in =media-libs/libgphoto2-2.4.1-r1 and =media-libs/libgphoto2-2.4.1-r1.
Both versions have /etc/udev/rules.d/70-libgphoto2.rules with structure:

# do not edit this file, it will be overwritten on update
#
# udev rules file for libgphoto2 devices (for udev 0.98 version)
# Created from this library:
#   libgphoto2      2.4.1          i686-pc-linux-gnu-gcc, ltdl, no EXIF
#   libgphoto2_port 0.8.0          i686-pc-linux-gnu-gcc, ltdl, USB, serial without locking
#

SUBSYSTEM!="usb|usb_device", GOTO="libgphoto2_rules_end"
ACTION!="add", GOTO="libgphoto2_rules_end"
...
GROUP="plugdev"
...
LABEL="libgphoto2_rules_end"

This rule still sets the group for all usb devices to plugdev and also overwrites GROUP="lp" for usb printers.

(In reply to comment #8)

Please provide emerge --info. I've tested this a different machines with difference settings: directory and/or template or all cameras or canon and ptp and in all cases I didn't have the broken rule.

% emerge -pvt media-libs/libgphoto2

These are the packages that would be merged, in reverse order:

please don't put informations you're asked on external websites, there is plenty of space in our server so that emerge --info or build logs can be hosted here.

[Comment 12 Gilles Dartiguelongue (RETIRED) 2008-08-03 22:13:13 UTC]

Ok udev rules are broken by template driver it seems. I'll try to fix that quickly and see if 2.4.2 fixes that.

CAMERAS="template" emerge -1av libgphoto2

[Comment 13 Gilles Dartiguelongue (RETIRED) 2008-08-04 22:03:03 UTC]

hopefully this is fixed with 2.4.2. Some parts of it has been rewritten and I couldn't reproduce this problem.
