I've tried also the csv version of libmtp, but it is the same

I was able to lets the mtp-detect and mtp-connect work. But this happens 1/10 tries and only if I run the mtp command as soon as the device is plugged on my laptop. After the run of first command the connection to the device fail and I have to un plug and replug the device

I don't know if the problem is involved on honeycomb or on samsung kies implementation. As I plug the device on the laptop the tablet run the kies software.

is it a problem kies side ? On 5 august there should be the upgrade to touchwiz ux ... hope will be also some change on mtp tablet implementation... if some tablets works and others not is it strange... but the most strange thing is that on windows it works

Just upgraded with the new samsung firmware but unfortunately it's the same problem. mtp-detect is able to connect only once wright after you plugin the tablet in the usb, after that it just times out.

i've just upgrade the firmware with the OTA update that include touchwiz ux

the problems still exists..

now mtp-detect give me the following output

mtp-detect

OK.

if I run the command as soon as I connect the device to the laptop I get the following output with an error at the end

Can you please append the mtp-detect output as an attached file to this bug so I can download it?

The following looks very worrying:

This is not the Android MTP stack but some custom Samsung stuff. Also it implements a fairly strong DRM variant, which may mean that this device neeeds to communicate with Microsoft DRM servers before you can access the content. In that case you cannot use libmtp with it, and the matter need to be discussed with Samsung.

I don't seem to have permissions to attach file but here is a link http://uploading.com/files/be3fmm21/mtp-detect.txt/

The thing is that I can connect to the tab without problems from windows xp without even installing the Kies application (which is complete garbage). I only needed the drivers from Samsung and the tablet shows as a regular MTP device.
The only thing that I noticed is that when plugged in linux and mtp-detect connects to it I don't see the tablet switching to the kies mode while it does that whenever I connect it to Windows.
I wonder if there is some command that needs to be sent to the device the first time it connects to keep it from blocking further requests.

I get the same output reporting microsoft extensions on my Samsung Galaxy S, and this issue seems to affect other devices.
See:
https://answers.launchpad.net/ubuntu/+source/libmtp/+question/149587

According to http://www.progweb.com/modules/blackberry/index-en.html the Blackberry also contains theses extensions also. Perhaps that is what the Black Berry switch mode magic bypasses somehow???

(I have no experience developing usb device drives this is just my observation)

After some experimentation, it seems to me that this is more of a timing issue. E.g., the following seems to work:

• kill gvfs-gphoto2-volume-monitor to avoid any interference
• connect the Galaxy Tab
• wait 2-3 seconds
• run mtp-filetree from libmtp git

As a result, I get a full listing of all files on the device. Haven't tried mtpfs with the git version yet, will do that next.

Yeah, I can only connect to it in the first several seconds after the tablet is connected via USB, then it just times out.
Try running the mtp-filetree again and I suspect it would timeout.

Try to have a hogging client like Gnomad2 or Rhythmbox active when plugging in. That will hog the device immediately and not allow it to time out.

SInce Windows hogs to the device without any program being active, that is closer to how their software stack works.

Using commandline programs and closing the device is never really tested on Windows.

Here is a link to a usb sniff of the tablet connecting and getting a directory listing on Windows: http://www.mediafire.com/?qj6jh4g3963kogq

The zip contains exports in different format and the original file created by USBLyzer.
There was no other device on the usb hub so all traffic should be related to the tablet.
I did not have to install Kies or anything other than the automated driver setup in Windows 7.
Hope this is helpful.

Another note, the device wouldn't open until I unlocked the tablet, before that the USB device was there but the view files dialog would not show.

I've added som autodetection stuff to handle Android devices, maybe it works better these days?

Regarding the comment about Microsoft DRM, it seems to me that the DRM isn't that restrictive (at least for my own content on the device, like photos and recordings which I'm only interested in).

I've tested this on a Windows 7 64-bit disconnected from the network, and I was able to plug my Samsung Galaxy S II (with Android 4.0 update), open it in Windows Explorer, and copy all kinds of files from it without requiring any contact with Windows DRM mothership servers.

If it really requires such contact, it is probably only for files which are specifically DRM-protected (like probably the stuff obtained through those cheesy Samsung **Hub apps that I didn't even bother to run).

If this can be of any help, I could try to perform a USB sniff of connecting and downloading a file of a specific type for you.

I propose one of two methods:

1) Native MS Windows USB log ( http://blogs.msdn.com/b/usbcoreblog/archive/2009/12/04/etw-in-the-windows-7-usb-core-stack.aspx ) that can be analysed with Microsoft Network Monitor like an ordinary network sniff dump,
2) Busdog sniff ( http://code.google.com/p/busdog/ ) - not preferable, since I'd need to mess with boot options and an additional system driver.

If you are interested, please specify the preferred sniffing method and what actions should I try to perform. I think that it would be reasonable to perform several separate cycles of connecting the device, navigating to a specific folder, downloading or uploading a single file of a specific type (e.g. jpg, mp3, avi or a generic random binary .dat) in the given cycle, then immediately disconnecting.

What do you think?

I think this is fixed in libmtp 1.1.3+ by some broken size fixes for Samsung,

Please retest!

Still a no-go. Detects the device but cannot connect, attempts to reset the usb port and fails attempting to find the port.
Debian 64bit
libmtp 1.1.3-35

Yeah. I'm using Ubuntu 10.10 Maverick, have compiled libmtp 1.1.3 from source. but detect not happening with my galaxy tab 10.1 (p7500). WHat's up? can connect using xp jsut fine.

This device should work now, please verify with 1.1.5.
