Need help linux computer has defect MTP connection [answered]

Yes, i believe above should work. I used to be Mint 13 KDE and kio-mtp package helped me to connect to my Dad's Android phone.

http://forums.linuxmint.com/viewtopic.php?f=56&t=142915

@wanderer and @anandrkris does this kio-mtp works with your jolla phone? could you confirm it?

thanks both of you, i'll try it this evening (i'm not at home).

@cemoi71 - Am on Mint Cinnamon now so unfortunately can not confirm. When connected via USB to Jolla, Cinnamon threw some crazy errors but I was able to mount finally somehow.

mint cinnamon? mean not anymore on mint 13, right?

Yes am on 17.1 Mint Cinnamon Rebecca. I mean, i moved away from KDE to Gnome based Cinnamon.

do you think is better than kde? i made the contrary, i was on cinnamon with mint 13, and now i'm now with kde on mint 17. :-)

@cemoi71: Yes, connecting my Jolla with kio-mtp works quite good. Sometimes it takes a few seconds to establish a connection but it usually works. One problem is that KDE somehow identifies the Jolla as an MTP-device as well as a PTP-device (the protocol used in digital cameras). However the PTP connection is not working, so you have to choose the right connection.

For Gnome MTP support is implemented in the package gvfs-backends in debian. Don't know if Cinnamon also uses gvfs.

@wanderer i'll try it out this evening, thanks a lot for this .

kio-mtp don't works, and with gmtp detected USB device will be directly disconnected

Oh, I'm sorry for this. What packages concerning mtp do you have installed? Please post the output of dpkg -l |grep mtp.

@wanderer thanks for the command, i'll try it this evening. I want to eliminate the possibility of a software issue too.

@wanderer the dpkg command give back gmtp libmtp-common libmtp9:amd64. i see with dmesg that the Computer disconnect the device after detection. Don't know why. I've tried all the usb port of computer, and different cables. but i can't eliminate software and driver issue

Does this disconnect issue always happen when you connect your Jolla via USB? I don't know what the reson for this could be.

For debugging you could try to use the App "USB-Switch" from Jolla Store. With this app you can switch between the USB modes charging, MTP connection and Developer Mode (if you have activated it) without having to unplug the USB cable. Then you can check again what dmesag says.

You could also check the output of the command "lsusb". It should output the following device IDs of your Jolla:

In Charging Mode: ID 2931:0a05

With MTP connection: ID 2931:0a05

In Developer Mode: ID 2931:0a05

@wanderer i saw yesterday with lsusb id is still the same in charge mode as in connection (not in devel mode, i didn't ry it). I'll try it again with the app that you mentioned. may i ask you to show by you which package you have, and tells me maybe which one is too much or what is missed? thanks in advance.

@wanderer hmm just one thing that i forgot to mentioned. I had just one time on a port (direct on computer ) that it displayed in dmesg report a " nss-myhostname is not installed" warning. Device was mounted, but explorer could not access to a formatted "container".

Sorry, I made a mistake in my last comment. I copied three times the same ID. The IDs should be like this:

In Charging Mode: ID 2931:0afe 
With MTP connection: ID 2931:0a05
In Developer Mode: ID 2931:0a02

My installed MTP Packages:

ii  kio-mtp                0.75+git20140304-1     amd64
ii  libmtp-common    1.1.8-1                       all
ii  libmtp-runtime      1.1.8-1+b1                 amd64
ii  libmtp9:amd64     1.1.8-1+b1                 amd64

I don't know if libmtp-runtime is a required package. Is your version of the libmtp packages the same or newer? I think as long as it is not much older it should be fine.

I have tried it now, with latest update of Sailfish and it still works normally as before...

@hyper_sonic could you please give more details?
Have you got a similar problem? could you use mtp or not?
You know, with your answer, we can't know if you want to help or if you need some help?
The only thing that correct is, you are in the right thread
And you give a lot infos.
Maybe you could give all the mtp packages name that you have in your distribution after giving the command dpkg -l |grep mtp,
thanks a lot for your participation.

On this host Android devices ZTE, lenovo works as expected.

@hyper_sonic seems to be that by me the problem is resolved. I want to observe further before i cry hourra!
seems now that i have more or less the same packages than by you on the computer
The only thing that i find that was crucial, was to reboot the jolla-phone. then worked on usb plugging...
If it don't work by you after reboot. Maybe would be fine to ask by jolla care
Seems for me that mtp interface on jolla device is not 100% clean.

@pmelas i have seen complete at the end of the header-file of the link that you gave, that the id for jolla is 0a05, and i have 0afe.
do you think that i have bad libmtp? or there is a conflict between libmtp-common and libmtp9?

I found this thread link text. And there it talks about the ids of the device on mac. Seems thtat it have changed on the past.

@eric@Simo@chemist may i ask you please please make a quick control what is the correct device idproduct for the mtp connection with the jolla-phone? please
I see on my computer that it gives with dmesg idProduct=0afe and seems to be for some people 0a05. Want to know if the libmtp on my computer is buggy, outdated or in conflict...
I can't have a proper mtp connection on my linux machine.

@pmelas wanderer has made a remark, that show it more plausible comment from him above

In this way that could means that my id is not bad, the device went only back to the charging mode, with its dedicated id...

Thank you, for link. But, I know about this hooks and applied it already. Device recognized by udev, and libmtp, but userspace file-system do not work.
