mtp problems

kokoko3k · 2013-07-27 09:34:25

In the past i could access my canon camera without problems in kde.
Now dolphin displays nothing about it, empty folder.
The same thing happens with galaxy s2
...it works good with a sansa clipzip.

mtp-detect only detects the sansa clipzip; nothing about the camera or the phone.
my system is fully upgraded and i can reproduce the issue on 3 different arch machines (a laptop, a desktop and a netbook)

Any hint or some idea to debug please?

-EDIT-
Tried as root, and got the same.

-EDIT
As soon as i attach the camera:
tail -f /var/log/everything.log

Jul 27 13:44:33 localhost kernel: [11997.652330] usb 1-6: new high-speed USB device number 9 using ehci-pci
Jul 27 13:44:33 localhost mtp-probe: checking bus 1, device 9: "/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6"
Jul 27 13:44:33 localhost mtp-probe: bus: 1, device: 9 was not an MTP device

...but it IS an mtp-device

Do you have the latest libmtp ? Have you tried alternatives to mtpfs ? Personally, i use jmtpfs (aur) with my HTC One and works flawlessly. Mtpfs breaks the shell is run from, and go-mtpfs (mtpfs client written in go - available on aur) is too big (go + itself >= 200 mb).

THanks, but correct me if i'm wrong:
all that packages relies on libmtp, (i just tried mtpfs, same issue).
and the message in my logs saying the camera is not an mtp device are from mtp-probe ; part of the libmtp package.
I think that the root of the problem is right in the libmtp, but i wonder if i'm doing something wrong or libmtp is just broken and i should report this upstream.

My system is upgraded, so libmtp is the latest; i also tried libmtp-git.

Anybody with a working "samsung galaxy s2" or "canon powershot sx200 is" mtp connection?

MTP is a big mess. The best way to sync your files to and from phone is the BitTorrent Sync.

I have the same problem as you:
using mtp with a samsung galaxy s2 does not work anymore. Last time it worked was about 2 weeks ago. Not sure what changed.

Well, then probably it is not libmtp, as i already tried to downgrade it to 1.1.5 (previous to your 2 weeks), without success.

I have a Nexus 4 which I can access through Nautilus without any problem. The only package I installed was gvfs-mtp (along with its dependencies). No configuration was needed either.

@bobzxr:
Is your system updated?
If yes, could you please check if in your /var/log/everything.log there is an entry like this:

Jul 27 13:44:33 localhost mtp-probe: bus: 1, device: 9 was not an MTP device

It appears to me as soon as i connect the camera/phone

thanks!

-EDIT

Nexus is another story, for me mtp works for some devices (sansa clipzip mp3 reader works), and not for others (galaxy s2, canon powershot sx200 is)

Men... i took a look to the libmtp code and i can confirm:

Implementation is a bunch of fixes and patches to make things work. I don't know what broke my setups, but i can understand why!
