GNOME Bugzilla – Bug 543938
MTP device (Sony NWZ-S616F) - Banshee says it can handle only one device at the same time.
Last modified: 2009-12-25 17:35:59 UTC
Please describe the problem: When I try to use my Sony NWZ-S616F with banshee it says it can't handle more than one device at the same time. This device can be used both as mass storage device and MTP device. I've used it with MTP in other players (Rhythmbox, Amarok) and it worked. I tried to disable one of the device plugins (mass storage and mtp), but the error persisted. Steps to reproduce: 1. Have the player connected when you open Banshee or connect it when Banshee is executing. Actual results: A pop up dialog is shown saying that the device will be ignored because banshee can handle only one device at a time. Expected results: I expect the device to be connected through the MTP protocol, allowing me to transfer music files to it, and remove files which are stored in it. Does this happen every time? Yes. Other information:
This occurs with my Sony Ericsson W910i as well. There is no debug output from the command "banshee-1 --debug --debug-addins".

I have checked it and there are no duplicated extensions! I had already tested to disable the mass storage media player support extension because I thought that the problem could be caused by conflict between the extensions, but the problem persisted.

Of course it was plugged. I can see references to my device in the lines: 1: udi = '/org/freedesktop/Hal/devices/storage_serial_Sony_WALKMAN_BEBE05355400' info.vendor = 'SONY' (string) ... info.product = 'WALKMAN' (string) ... 2: udi = '/org/freedesktop/Hal/devices/usb_device_1d6b_2_0000_00_02_1_if0_0_scsi_host_scsi_device_lun0' scsi.vendor = 'SONY' (string) ... scsi.model = 'WALKMAN' (string) ... 5: udi = '/org/freedesktop/Hal/devices/usb_device_54c_327_BEBE05355400' ... info.vendor = 'Sony Corp.' (string) info.product = 'WALKMAN' (string) ---- OK, maybe it's harder to find it if you don't know its a Sony Walkman and don't search for the string "SONY" and "WALKMAN". I will send the output generated in another computer together with the lshal output which can be useful to you also.

I have been having a look at this with my Sony Ericsson W910i and this is what I have found. I put some debugging code into the MtpSource.cs routine (Patch Attached) and work out where the problem for my device actually occurs. This is the output from the Debug Code. PTP: Opening session [Debug 01:00:27.392] MTP Device count is (1) [Debug 01:00:27.392] MTP Device [Debug 01:00:27.393] Device Serial Number is (00000000000000000358875016410675) [Debug 01:00:27.394] Device Version is (1.10) [Debug 01:00:27.394] Device Name is (W910i) [Debug 01:00:27.395] mtp_serial is (00000000000000000358875016410675) [Debug 01:00:27.395] device.Uuid is (3588750164106750) [Debug 01:00:27.395] mtp_device is null PTP: Closing session It looks to me like the device is being detected correctly but the serial number is being truncated by one character, therefore does not contain device.Uuid. This causes mtp_device not to be set, which inturns is detected as Null. I am currently running a SVN code (post 1.0.0). The SVN revision is 4242. I have attached: 1) The patch with the debugging code. 2) hal-device for my PC. If you want any more information, just ask. BTW, this is the first time I have touched C# and if the patch looks awful, i apologise.

This may be a libmtp problem.

> > These output show that banshee is not manipulating the serial numbers in any > way, therefore my summation that it could be a libmtp problem. > I don't think so. At least for my device the problem doesn't seem to be in libmtp. I tested Amarok and Rhythmbox. Both use libmtp and my device works right with them. If the error is in libmtp then it is not caught by these applications or they use some workaround to bypass the problem.
The reasoning behind my summation, about libmtp, is that the code requires the serial number from the USB device matching part of the serial number from libmtp. If there is a match a pointer gets set and it these are not a match then the pointer does not get set and the error message is produced. I have had a look at the rhythmbox code and it does not do this check and yes my device works fine in rhythmbox. Although I find C++ more difficult to read then C#. I am going to pose the question about the serial numbers to the libmtp discussion group, to see what sort of response I get. Do you have mtp-detect on your system? If you don't have this then gphoto2 --summary will suffice. Can you run it and post the output from it with the dmesg output?
Hi. I filed a bug in the libmtp Sourceforge tracker asking to add my device to the list supported by libmtp. The output of mtp-detect can be found there. They said that my device is supported by the cvs version of libmtp, maybe you can test with that version. https://sourceforge.net/tracker/?func=detail&atid=809061&aid=2019026&group_id=158745
(I'm a developer on libmtp) First, last time I checked, Banshee was using libgphoto2 to interface MTP devices, not libmtp. Has this changed? The serial number at the USB level obviously differs from the one at the MTP level. This is probably a firmware bug. libmtp 0.3.0+ has a safer way of identifying a device by using the raw device descriptor, which gives the device physical attachment point in the USB hierarchy. And it can also handle multiple devices... I would migrate to libmtp 0.3.0 (Amarok 2.0 will use it too) ASAP as this solves this and a few other issues as well.

I am willing to know if libmtp 3.0 a and Banshee will handle folders the right way for my device. I was looking for using Banshee because I am trying to find a player which works well with directories for albums and artists. But i couldn't test it yet because of this bug. Amarok has support for creating folders but the stable version creates repeated folders in device.
FYI... I'm having same problems with a Palm Treo680 and pocket tunes. Running Ubuntu heron and Banshee 0.13.2.

Has anyone successfully got a sony nwz device working with banshee and mtp? Are there any hacky workarounds that I could use for now?
Here's a patch which bypasses (fixes?) the problem for me. I'm unsure if this bug only affects sony walkman products, so i've left the original logic in place for other manufacturers, but for sony at least, it seems the check is backward. For me: mtp_serial is (00000000000000000000000005453003) device.serial is (10FA17D5453003)

First of all, that patch doesn't work like that. You forgot to close one set of parentheses and to open the curly bracket on the first line of additional code. I used the patch against banshee-1.5.0 and then tried hooking up my Sony Walkman NWZ-S639F. It still does not connect.

Hmmm... if mtp-detect isn't connecting, then I'm guessing it's a different bug to the one I've been seeing. For me (and the supplied patch), mtp-detect works fine and returns the expected output. I think you must be running into a different bug with libmt8 itself.

Comment on attachment 143024 [details] [review] updated version of the patch Committed, thanks Nyall.
I see this bug is resolved but since I'm seeing this behavior under Ubuntu Karmic (9.10) and latest release of Banshee (1.5.2) downloaded from the developer's ppa, I figured I'd post here rather than open a new ticket. MP3 hardware is a Samsung YP-S3 with firmware 1.12. All mtp utils functions work and I can access the device via Rhythmbox or Gnomad2. One thing I've noticed about the mtp lib is that if the device is open in Rhythmbox, I cannot use the mtp utils. Not sure if this is a symptom of a bigger issue or expected behavior.
