[SOLVED] libmtp problems

fettouhi · 2008-04-18 09:31:43

I'm having problem with libmtp on my Arch Linux installation (32-bit). I have a Creative Zen Vision M:60 GB mp3 player and that uses the mtp protocol to sync with my machine. The problem I'm having with libmtp is that if I plugin my mp3 player and try to sync with Amarok or Gnomad2 nothing happens. If I run Amarok or Gnomad2 as root then it works. I checked that my user is a member of the "audio" group and I set the policies in udev.rules so that the "audio" group can use libmtp but still I can only sync as root UNTIL I restart the machine or plug the player in before I can start my PC. I have no clue what's wrong here, why I have to restart my pc in order sync my mp3 player as a user.

Regards

André

I used to be able to sync my iRiver Clix through Amarok just fine (dunno how that was for you). On this new laptop however I had a similar problem. I tried to assign the device to the storage group (it gets assigned to 'camera', but only the root device), but the subdevices still get assigned to a different group somehow. I ended up just assigning it to my user (I am the only one using the device anyway, and it's just me on this laptop too).

# iRiver Clix - seems we need it after all...
SUBSYSTEMS=="usb", ATTRS{manufacturer}=="iriver Limited", ATTRS{product}=="iriver clix", SYMLINK+="libmtp-%k", OWNER="stijn", GROUP="storage", MODE="0660"

Kind of hackish, but it surely works. I presume something has changed in the stock rules that Arch ships with over time and I'm too lazy to go find out, frankly.

Already tried that already and it doesn't work. I still have to restart my machine if I want to sync my mp3 player as a user.

Well then you need to show us how your perms are. Care to list them on the device, and show us your udev rules? I presume you tried unplugging the device and plugging it back in?

fettouhi · 2008-04-19 12:07:19

Yes I tried that . Here is the udev rules for my device.

# Creative ZEN Vision:M (DVP-HD0004)
ATTR{idVendor}=="041e", ATTR{idProduct}=="4151", SYMLINK+="libmtp-%k", MODE="666", GROUP="audio"

I'm having this exact same problem with my Creative Zen Vision: M 30gb

running:

sudo /etc/start_udev

makes my Zen Vision:M viewable by mtp-detect once again but it breaks my openGL so I'd rather it just work on boot.

my udev rule:

ATTRS{idVendor}=="041e", ATTRS{idProduct}=="413e", SYMLINK+="libmtp-%k", MODE="666", GROUP="audio"

No fix yet, this had worked no problem for over a year.

.:B:. · 2008-04-19 23:07:41

That's probably due to your chmod 666 rather than to your audio group. I had it assigned to groups I belong to (first camera, then storage) and none of it worked. Try resetting the perms on your device to 660 and see how it goes .

@ Fettouhi: did you try setting the OWNER= variable?

@ B: I'll try that again.

fettouhi · 2008-04-20 07:41:11

Well, that didn't change anything. mtp-detect gives

[af@andre ~]$ mtp-detect
libmtp version: 0.2.5

Attempting to connect device(s)
usb_claim_interface(): Operation not permitted
LIBMTP PANIC: Unable to initialize device 1
LIBMTP PANIC: configure_usb_devices() error code: 7 on line 1561
Detect: There has been an error connecting. Exiting

but doing sudo mtp-detect connects to my ZEN.

.:B:. · 2008-04-20 11:45:47

Ok - maybe you can try the 2.6.1 package (don't think it should change anything but heck, who knows?):

Get it here (i686 package).

fettouhi · 2008-04-20 15:25:24

Nope, doesn't change a thing upgrading libmtp. There must something wrong with dbus or hal in my installation because my GNOME installation is all screwy. I was running KDEmod before and then I installed GNOME 2.22 and since then my desktop has been a mess. Here is my modules list from rc.conf

MODULES=(forcedeth slhc ac97_bus snd-mixer-oss snd-pcm-oss snd-seq-oss snd-seq-device snd-seq-midi-event snd-seq snd-page-alloc snd-pcm snd-rawmidi snd-timer snd snd-mpu401-uart snd-mpu401 snd-ac97-codec snd-intel8x0 soundcore fuse vboxdrv)

and daemon list

DAEMONS=(syslog-ng network netfs crond alsa hal fam wicd cups samba stbd).

I think this is a problem with UDEV, not lib mtp. I've been hacking apart the rules with no luck so far.

The fact that it works after a UDEV restart, and that apparently it works if the device is plugged in when the computer is turned on... seems to be an issue with hotplug functionality.

uastasi · 2008-04-22 17:10:06

Try in this way:

cd /etc/udev/rules.d/
mv udev.rules.pacsave udev.rules
killall udevd
/etc/start_udev

patroclo7 · 2008-04-23 06:38:19

The libmtp source package includes a complete set of udev rules for libmtp devices, which are installed by a script called hotplug.sh. The script is rather interactive and proposes to install also the old hotplug stuff and the support for hal (which would create an unwanted dep)., so I guess that it can not used in the package, but perhaps the udev rules could be installed explicitly in the PKGBUILD in /etc/udev/rules.d. If I am not the only one to think that this is a good idea (something like this is already done for analogous libraries, such as libnjb) I can post a bug.

.:B:. · 2008-04-23 09:12:37

Definitely. If it comes with udev rules, the PKGBUILD should install them into the package in a verbose manner imho.

Please, mark it as [Solved]

Kurous · 2008-04-23 16:41:42

Fixed here as well. Why was udev.rules removed??

.:B:. · 2008-04-23 17:41:18

o_O

I have no such thing, not even after a reinstall:

[root@hermes stijn]# ls /etc/udev/rules.d/
05-personal.rules                           60-cdrom_id.rules                           75-persistent-net-generator.rules.optional
05-udev-early.rules                         60-persistent-input.rules                   80-drivers.rules
40-pilot-links.rules                        60-persistent-storage-tape.rules            90-hal.rules
50-udev-default.rules                       60-persistent-storage.rules                 95-udev-late.rules
51-arch.rules                               61-persistent-storage-edd.rules             99-fuse.rules
53-sane.rules                               64-device-mapper.rules                      bluetooth.rules
54-gphoto.rules                             64-md-raid.rules                            device-mapper.rules
55-hpmud.rules                              75-cd-aliases-generator.rules.optional

Edit: wait - that means the new rules broke the permissions. Can someone diff both files? I guess my box (and thus my install) is too new to have any of those udev pacsave files...

Would be very much appreciated .

I never had the udev.rules file before either, I simply copied over the pacsave file.

rules.d]$ ls
05-udev-early.rules               61-persistent-storage-edd.rules

45-libnjb.rules~                  75-persistent-net-generator.rules.optional
50-udev-default.rules             80-drivers.rules

60-persistent-storage-tape.rules  udev.rules.pacsave

.:B:. · 2008-04-23 21:07:22

Hrm... I just had the udev.rules, nothing else. I checked the cvs of the udev package, the differences with previous versions of the udev.rules files, but nothing that seems to relate (at least not directly).

fettouhi · 2008-04-29 13:21:01

I just did a fresh install of Arch and I don't have the udev.rules or udev.rules.pacsave at all. Can someone post the udev.rules file please?

Re: the above link:

Unknown post id, it may have expired or been deleted

How do I check what the rules are for my device (a Zen V+)? Presumably, I should be able to add myself to the right group if I figure out which one it wants me to be in.

Running gnomad2 as root is the only way the system will allow me to access it, at this point. As a normal user, I get:

usb_claim_interface(): Operation not permitted
LIBMTP PANIC: Unable to initialize device 1
LIBMTP PANIC: configure_usb_devices() error code: 7 on line 1599
LIBMTP_Get_First_Device: Error Connecting
PDE device NULL.

How can I fix this? Sorry if my question seems noobish
