hotplug scripts are not installed

[Jelmer Graafstra]

The hotplug scripts provided with the gnomad2 source (or an alternative) are not installed with the package. As a result, file permissions are not set correctly when the player is plugged in, so only user 'root' will be able to access it.

[Douglas Anderson (douglas-anderson)]

I think the severity level should get bumped up, considering that doing 'sudo apt-get install gnomad2' is just about guaranteed to install a broken program. It has been a recurring problem for me throughout multiple installs.

Running Gnomad2 from the applications menu after a flawless install still throws the "Could not open jukebox:usb_set_configuration: Operation not permitted" error.

Though the workaround is simple enough, for people not familiar with searching forums and bug trackers, the program and their mp3 player is rendered useless. Big problem.

[Lionel Dricot (ploum-deactivatedaccount)]

We don't use hotplug anymore. I close this bug. Feel free to reopen it (or open a new one) if the application is still broken.

[Richard Quirk (quirky)]

Adding the appropriate /etc/hotplug/usb scripts by hand fixes the "root only" problem, so it seems Dapper does still use hotplug.

[Richard Quirk (quirky)]

OK. So I've been investigating a bit. The apropriate udev scripts are present in /etc/udev/rules.d/45-libnjb.rules.

These correctly set the permissions on /dev/bus/usb/00x/00y to root:plugdev and 0660 and my user is in the group plugdev. I can't seem to repeat the problem after having used the old hotplug scripts, even though I have removed them now. But the first time I plugged the zen in, it gave this error message.

[Richard Quirk (quirky)]

The problem is now only seen if you start the PC with the device plugged in. Once you unplug it and re-insert it, then the correct udev rule is called, device (/dev/bus/usb/N/M) changed correctly, etc.
i.e. Works as expected in Dapper.

You have to let the kernel experience a hotplug event (deplug/replug)
before any hotplug/udev scripts take action. They only run when the
device is attached.

This means there is no script that performs "coldplug" i.e. check for
present USB-devices when the machine is turned on. Fedora calls all udev
scripts once during boot, it might be that Dapper doesn't.

I am using dapper with gnomad2 version 2.9.0 installed from source (together with the latest libnjb and libmtp, of course). the scripts are installed, but libmtp.rules or nomad.rules are missing the entry for my Creative Zen Micro 6GB, for which I was able to find the numbers, using lsusb command, and then added the appropriate line(s).

The problem is that gnomad2 will run only in superuser mode, i.e. when I run from terminal for example:
sudo gnomad2
or in a launcher:
gksudo gnomad2.

================

here's more:

when i run as normal user i get "No jukeboxes found on USB bus".
but when i run as superuser gnomad2 works fine.

here's my command-line output when i try to run gnomad2 from console:

usb_claim_interface(): Operation not permitted
LIBMTP PANIC: Unable to initialize device 1
LIBMTP PANIC: configure_usb_devices() error code: 7 on line 1561
LIBMTP_Get_First_Device: Error Connecting
PDE device NULL.

=================

and even more:

well, when i run gnomad2 as user, i tail those messages with:

tail -f /var/log/messages

i get:

usb 4-3: new high speed USB device using ehci_hcd and address 2

and, when i run as superuser/sudo, i get:

usb 4-3: reset high speed USB device using ehci_hcd and address 2

See the difference? It's just one word.
In case of a normal user is "new", while as a superuser is "reset".

===========

now, please let's find out the problem, because I've tried everything posted in this thread and many others, and I could not make gnomad2 run in normal user mode - only in superuser mode.

thank you very much for understanding.

This is the real problem.

* Which version of libmtp are you using? (if < 0.2.5, upgrade)
* If installed from source, did you run hotplug.sh after install?

Linus

[dstoian (dstoian)]

thanks for the reply, Linus!

i have libmtp version 0.2.5, libnjb version 2.2.6, and gnomad2 version 2.9.0.

yes, i did run the hotplug.sh script - and i have the libmtp.rules and nomad.rules files under: /etc/udev/rules.d

one or the other "rules" file was missing an entry for my device Creative Zen Micro has device id 4130 so i had to add it where it was missing.

i found my device id like so: lsusb | grep Creative
which returns: Bus 004 Device 006: ID 041e:4130 Creative Technology, Ltd
so vendor id is 041e and device id is 4130.

any more thoughts? so many people out there have the same problem, i've read about this on so many forum threads.

thank you,
dan

Only libmtp.rules should have this device, it is MTP only, libnjb.rules
has no use for it. And it should have that entry.

The problem is somewhere in your distributions hotplug/udev mechanisms. I
don't know enough of Ubuntu to know how it is set up, this is distribution
specific to a large extent, sorry.

Linus

[dstoian (dstoian)]

that's ok, i can live with it for now.

just a note: there is no "libnjb.rules": only these two:
- libmtp..rules. and
- nomad.rules.

thanks

This still occurs the first time you attach a nomad jukebox in gutsty.

I found out recently that Amarok can do a very good job at managing MTP devices. Hmmm! Nice.
I tried it in Ubuntu 8.04 and it works fine with my Creative Zen Micro.
