[Bug 67532] Re: udev-rule for PTP class detection broken

[Martin Pitt]

Edgy goes out of support in about a month, so it's not worth doing such
a fix now (especially since it has never been pinned down properly and
attempted to get fixed several times). It has been fixed properly in
Feisty (7.04) and beyond.

RE: [Bug 67532] Re: udev-rule for PTP class detection broken

[nobtiba]

Hi,

Thank you for suggestion. In fact, i tried to work with fuser but not sure what 
to replace /dev/usbx
From: gphoto2 --auto-detect i get:
Model  Port
--
Aiptek Pencam  usb:
Aiptek Pencam  usb:001,020 
Aiptek Pencam  usb:001,019 
I tried

fuser -uv /dev/usb:001,020 but it said
Cannot stat /dev/usb:001,020: No such file or directory

Then I tried:

fuser -uv /Aiptek Pencam
fuser -uv /dev/usb/Aiptek Pencam 
fuser -uv /AiptekPencam

but no one seems to be the right command.

So could you tell me a bit more detail how should i do to debug the
error since i was only a beginner

Thank you !

[Bug 67532] Re: udev-rule for PTP class detection broken

[Peter Whittaker - no longer all that active]

Brian, thanks for your assistance, you were right, this is indeed a
different bug.

Folks, the camera works fine for all users of this machine except one,
whose ${HOME} and all .g* settings were created under Edgy. I've created
new users on this machine and they see the camera just fine.

I suspect the problems I reported above may have something to do with
the path this machine took: Dapper install from CD, Edgy Beta upgrade
on-line, Edgy final upgrade on-line, Feisty beta upgrade on-line, and,
finally, fresh install from Feisty CD, overwriting /, leaving /home in
place. Somewhere in there, ~/.* settings got mangled and broke the
camera import detection for this one user. Definitely a different bug,
please disregard comments above (comment#40).

[Bug 67532] Re: udev-rule for PTP class detection broken

[Peter Whittaker - no longer all that active]

Brand new Feisty install (fresh this morning, with all updates applied).

Two users: Me, my daughter. I create my account during the install
process, add hers afterwards; she does not have admin privileges, has
all other privileges (including plugdev membership).

Login to GDM as me, plug in Kodak C533: Import dialog appears.

Login to GDM as her, plug in Kodak C533: Nothing. Nada.

Logged in as her, run gnome-volume-manager-gthumb from command line
without arguments. Receive following messages, but am able to import
photos

process 8234: arguments to dbus_message_new_method_call() were
incorrect, assertion _dbus_check_is_valid_path (path) failed in file
dbus-message.c line 1074.
This is normally a bug in some application using the D-Bus library.
libhal.c 939 : Couldn't allocate D-BUS message
error: libhal_device_get_property_type: (null): (null)
hal_get_property.c 178 : INFO: called LIBHAL_FREE_DBUS_ERROR but
dbusError was not set.

I've tried adding the ENV{} line to udev rules added immediately before
device specific rules, after gotos); tried setting the device specific
permission to 0666, tried giving her admin privileges, nothing works. By
nothing works I mean that the import dialog only appears for me and
not for her.

I've also verified /etc/passwd* and /etc/group* and everything looks
good (plugdev membership, etc.). But only my account, the first user
account (uid 1000) has success, her account (uid 1001) gets no dialogs
and the command line error above).

If this is another bug, let me know, I'll add this report to that bug.

This is different bug, I'm pretty sure.  I'll correspond with you and
try to work out a couple things,  but it might be a decent thing to file
a bug report about anyway.

The issue might be that the machine in question had edgy-backports (to
get working gphoto2 stuff), and edgy-backports and feisty has the same
libgphoto2-2 version.

[Bug 67532] Re: udev-rule for PTP class detection broken

[Niklas Edmundsson]

This is a machine upgraded from edgy, and doing dpkg-reconfigure
libgphoto2-2 indeed gives me a correct 45-libgphoto2.rules that has the
comment about being for a new udev version.

I suspect that when doing an upgrade it's still running the old udev-
version, and thus generates the file for the old version. When the
machine finally gets around to running the new udev version (it might
even take a reboot, I don't really know) it obviously will not work.

The kludge for the moment is of course doing dpkg-reconfigure on
libgphoto2-2, I was too tired and frustrated to even think of that.

In the long run this should really be fixed in some sane way, you really
shouldn't be expected to do dpkg-reconfigure on various packages in
order for stuff to work after an upgrade.

[Bug 67532] Re: udev-rule for PTP class detection broken

[Niklas Edmundsson]

Indeed, editing /etc/udev/rules.d/45-libgphoto2.rules and replacing BUS
with SUBSYSTEM makes it work.

Incidentally, this coincides with the output style from
/usr/lib/libgphoto2/print-camera-list udev-rules-0.98 which is supposed
to output a file usable by udev 0.98+...

Could it be so simple as libgphoto2-2.postinst being buggy? If I look at
/etc/udev/rules.d/45-libgphoto2.rules it says it's for (udev  0.98) but
the installed udev is obviously newer than that... If that's the case,
fix should be trivial. And developers should be embarassed ;)

This is on Ubuntu Feisty x86, libgphoto2-2 2.3.0-0ubuntu4, using a
Panasonic DMC-FZ5 camera (recognized as FZ20 I think).

On a clean Feisty install (from Desktop CD) the
/etc/udev/rules.d/45-libgphoto2.rules file uses SUBSYSTEM. After running
sudo dpkg-reconfigure libgphoto2-2, it's still SUBSYSTEM. I don't
understand why it doesn't work for you, Niklas.

Following aldegaz's instructions above, and changing the 3rd line in

SUBSYSTEM!=usb_device, GOTO=libgphoto2_rules_end

Fixed the problem with my Digital Rebel and PowerShot S500.  I didn't
really mess with my Rebel when working on this problem, but for the
PowerShot, I noticed about 5 repeats of the device ID in the rules file
for:

04a9:30b4 Canon, Inc. PowerShot S500

So it was always there in multiple!

[yct]

Exactly the same thing (as in the description of this bug) happened to
me yesterday with my Kodak EasyShare DX4530, and I had to do the
following downgrade to make it work again:

libgphoto2-2: 2.3.0-0ubuntu3~edgy2 -- 2.2.1-2ubuntu4
libgphoto2-port0: 2.3.0-0ubuntu3~edgy2 -- 2.2.1-2ubuntu4

To sum it up - it was working all the time, then after recent update it
stopped to work, and after downgrading the packages, it worked again
(immediatellly / no restart).

I'm not sure whether I should fill a new bug report for this.

I actually made it work just once and then the bug came back.

I finally found this that made all the difference in 2 computers with a
clean Edgy Eft 6.10 install:


replace the third line in /etc/udev/rules.d/45-libgphoto2.rules:

BUS!=usb*, GOTO=libgphoto2_rules_end

with
SUBSYSTEM!=usb_device, GOTO=libgphoto2_rules_end

It only worked when changing the permission to: MODE=0666

[Bug 67532] Re: udev-rule for PTP class detection broken

[baaz]

Is this really a bug or i it just that the list of known devices in
/etc/udev/rules.d/45-libgphoto2.rules is incomplete. I have a Canon
Powershot A640 and got the same error. What I did was this:

$ lsusb
Bus 004 Device 031: ID 04a9:3139 Canon, Inc. 

Then added the following line to /etc/udev/rules.d/45-libgphoto2.rules

SYSFS{idVendor}==04a9, SYSFS{idProduct}==3139, MODE=0660,
GROUP=plugdev

And everything works as a charm.

Cheers

For the Kodak Easy Share V610 it's only outdated

[Bug 67532] Re: udev-rule for PTP class detection broken

So all this just because libgphoto2 in the latest release of Ubuntu is
outdated? ;)

ii  libgphoto2-2   2.2.1-2ubuntu4 gphoto2 digital camera library

According to this page
http://dehs.alioth.debian.org/wwiz_detail.php?id=8454283type=up_changes
some new releases of libgphoto2 has been released since 2.2.1 =)

My camera was added in 2.3.0 (2006-12-03)

Re: [Bug 67532] Re: udev-rule for PTP class detection broken

I think there's actually some other issue with it - it's supposed to
recognize them more generally, or some such.  There's something on that
somewhere in this humongous bugreport, or in a bugreport linked to from
this one.

I agree that this really sucks in Edgy. However, I have to cook up a new
patch for Edgy.

Thank you so very much for your attention to this issue in Edgy,
Martin.  :-)  It's greatly appreciated.  I really hope to see Linux take
significant share in the desktop market, and I think Ubuntu is the
candidate for this; both for ease of use and for ideological standing.
Good luck!

 libgphoto2 (2.3.0-0ubuntu1) feisty; urgency=low
 .
   * New upstream version 2.3.0. Closes: LP#74847, LP#61163
   * Dropped almost all patches from the package diff.gz since they have been
 adopted or obsoleted upstream. Only remaining change:
 - libgphoto2/gphoto2-filesys.c: Do not cache all downloaded files to plug
   a giant memory hole (see Debian bug #372166).
   * packaging/generic/{print-camera-list.c,check_ptp_camera}: Applied upstream
 SVN change 9562 to add and use an udev helper script to detect whether a
 USB device has a PtP compatible interface. This cannot be matched with a
 simple udev rule. Closes: LP#67532
   * debian/rules: Install check_ptp_camera to libgphoto2-2's lib/udev/.
   * debian/rules: Remove the 'make all-local' call, it does not work any more
 and is not necessary any more either.
   * debian/*.files{,.in}: Turn versions in paths into globs to match newer
 versions.
   * debian/libgphoto2-2.postinst: Call print-camera-list with mode and group
 arguments (this replaces the former source code patch.)

Same here with a Canon EOS 400D (Digital Rebel).  I tried the general
rule

ENV{INTERFACE}==6/1/1, MODE=0660, GROUP=plugdev

first.  It did not work.  I added

SYSFS{idVendor}==04a9, SYSFS{idProduct}==3110, MODE=0660,
GROUP=plugdev

Now it works.  Thanks for the workaround.

unfortunately the ENV{INTERFACE} hack does not work, since iut happens not
in the device creation event.

I am using a check_ptp_camera helper script again in libgphoto2 2.3.1
(to be released)

Just for reference, I have a Kodak P850. This is how it identifies
itself:

Bus 003 Device 003: ID 040a:0592 Kodak Co.

I also needed to add rules to my udev rules.d. Note that I am running
Edgy, this really need to be there by default.. Perhaps there should be
a rule that just has the vendor id... There seem to be a lot of products
missing at the moment..

Daniel,

the rule for the device class as indicated by Marcus should be  enough
for all PTP camera.

BTW P850 is supported in 2.3.0.

[Daniel James]

Thanks for the info Hubert.

I just updated my udev rules and removed the rule specific to my camera.
Then I added the INTERFACE rule was mentioned by Marcus. I restarted
udev and plugged in my camera, this was the result:

An error occurred in the io-library ('Could not claim the USB device'):
Could not claim interface 0 (Operation not permitted). Make sure no
other program or kernel module (such as sdc2xx, stv680, spca50x) is
using the device and you have read/write access to the device.

It appears that my camera is not using that interface...
