Hi,

Here you can find the information provided by the latest version of Libmtp (through VirtualBox) with my Samsung Galaxy S2

libmtp version: 1.1.0

I think that this could be solved by adding support for the Samsung Galaxy Tab 10.1, since their device IDs are identical. Discussion about that is going on in tracker issue 3372454.

[Anonymous]

I can provide a USB capture from USBlyzer if you want, just ask me if you want it

[Anonymous]

I need more info to classify and possibly add this device.

• What does "mtp-detect" (maybe run as root) produce?
• What does lsusb -vv display for this device?

[frapell]

I'm having these exact issues with my Samsung Galaxy S2.

As per Issue #3372454 i tried running mtp-detect as soon as i plugged in the device and i got some useful output, but then i got errors for every time i tried it afterwards.

I also have some verbose output from lsusb.

mtp-detect : http://pastebin.lugmen.org.ar/6789 (Serial number hidden by me)
lsusb: http://pastebin.lugmen.org.ar/6790

PS: Any idea on how can i attach a file directly here instead of using pastebin ?

So this bug may be a duplicate of the Galaxy Tab 10.2?

Is this in Android 3 (Gingerbread) or Android 4 (Ice Cream Sandwich)?

I have a vague idea that Androids MTP stack is used from 4.0 forth and Samsung
used their own stack (with these issues) prior to that.

[Linus Walleij]

bongmaster: when you runt it in PTP mode, have you tried it with gPhoto2 without libmtp?

We have a few fixes in the git for this device since last week or so, can you
please check if it solves your problems?

[botusj]

Same sort of issues with the latest libmtp.
This took a long time to finish, maybe an hour or more.

Hm. have you tried this with the example program
mtp-filetree that access the device in the way that Android
devices prefer to be rubbed?

[Aleksander Adamowski]

Hi! I think it's not necessary to wait a full hour to finish it (I suppose it's some libmtp's timeout).

I've discovered that mtp-detect seems to output the same information when you physically disconnect the device some seconds after launching mtp-detect.

botusj, Nico, could you verify that you get exactly the same info when simply disconnecting the device (no stuff missing from the output)?

I also suspect that this issue is the same as described in this bug:

https://sourceforge.net/tracker/?func=detail&aid=3372454&group_id=158745&atid=809061#

that is, it's a problem with handling of Samsung's extensions to Android MTP stack (like the darned Microsoft DRM).

Maybe you can capture some USB traffic logs on Windows how it communicates with your device (using this: http://blogs.msdn.com/b/usbcoreblog/archive/2009/12/04/etw-in-the-windows-7-usb-core-stack.aspx or this: http://code.google.com/p/busdog/ )?

[Aleksander Adamowski]

BTW, I've tested using libmtp compiled from Git master today and the behaviour is the same. Verified using strace that mtp-detect and mtp-filetree actually link with the Git version of the library. They both hang after printing out "Attempting to connect device(s)".

[Linus Walleij]

I have the same issue on Ubuntu 12.04, S2 with Samsung ICS.
Trying with libmtp 1.1.5 (git f97c48f1f):

~/src/libmtp/examples$ ./mtp-connect

LIBMTP PANIC: failed to open session on second attempt
No devices.

I captured USB communication with usbmon, see attachment.

Please let me know how else I can help.

(update: sry, can't delete the duplicate attachment, seems to be a sf bug)
