I have an MTP device which is failing when trying to transfer the file from my collections to the device. The different software versions are: libmtp-0.1.3 and amarok-1.4-SVN
Here are some details about what is happening. I have connected the device using 'MTP Media Device' option and the mediadevice browser shows the playlists from the device. After that I selected a file from my collections and told it to 'Transfer to Media Device' at which point it queues it up in media devices Transfer Queue . Next when I try to 'Start Transfer' it gives an error message saying 'Failed to copy track ...' Here is the debugging ouput: amarok: BEGIN: virtual bool MtpMediaDevice::openDevice(bool) PTP: Opening session amarok: [MtpMediaDevice] setting default parent : 0 amarok: END__: virtual bool MtpMediaDevice::openDevice(bool) - Took 3s amarok: [MtpMediaDevice] Parent folder could not be found.

I went as deep as looking up ptp_sendobjectinfo and ptp_transaction but don't see any problem with the code in the library. So does it mean the hardware is broken ? The device works fine in MS environment. |

OK, did some more digging. Looks like there is some authorization related issue. Here is some info from mtp-detect:
Special directories: Default music folder: 0x00000000 Default playlist folder: 0x00000000 Default picture folder: 0x00000000 Default video folder: 0x00000000 Default organizer folder: 0x00000000 Default zencast folder: 0x00000000 Default album folder: 0x00000000 Default text folder: 0x00000000 libmtp supported (playable) filetypes: ISO MPEG-1 Audio Layer 3 Microsoft Windows Media Audio Microsoft Advanced Systems Format RIFF WAVE file When using mtpfs from http://www.adebenham.com/mtpfs/ , I can mount and do any activity only as root. The device permissions are fine: crw-rw-rw- 1 root root 189, 9 2007-01-26 04:00 /dev/bus/usb/001/010 <===========> /dev/libmtp-usbdev1.10 -> bus/usb/001/010 -cyrus |

Hm... Do you have the libmtp.rules-file in /etc/udev/rules.d/?
I don't know if this file is needed in recent libmtp-versions, but for version 0.0.20 it was, so it is available on my System since then and maybe libmtp 0.1.3 needs it too? It has to have the following content:
Mybe this solves your problem...
MacBook, 2GHz C2D, 3GB RAMM, 120GB HDD.
Amarok 2.0 Beta from KDE-on-Mac. |

I had the same problem trying to send tracks to a Clix using libmtp from CVS just after the 0.1.2 release. What works for me is changing the following in the libmtp cvs source: libmtp/src/ptp.h //#define PTP_USB_BULK_HS_MAX_PACKET_LEN 512 #define PTP_USB_BULK_HS_MAX_PACKET_LEN 4096 As you are using amarok-1.4-SVN and it is building mtpmediadevice w/o problem I guess MtpMediaDevice::getCapacity & MtpMediaDevice::customClicked() have been fixed. |

deloco, I didn't go into the details that I do have the udev rules file and /dev/libmtp... device links are being created with 666 permission and I can see the playlist in Amarok and I can delete files from my MTP device etc.
lrpstrcr, I tried your patch to increase packet length to 4096 but it still did not work (nor reducing it to 64), same error 'Failed to copy...'. I did try $mtp-sendfile Here is my mtp-detect output Found non-autodetected device "Nokia XXX" on USB bus... Connected to MTP device.

A major problem I am facing is when I click on a track on my MTP device, it does not play the track and gives the following error message. Does this happen with other MTP devices such as Clix or Zune ?
amarok: BEGIN: virtual void UrlLoader::completeJob() amarok: [PlaylistLoader] The following urls were not suitable for the playlist: amarok: [PlaylistLoader] file://Chiquita.mp3 amarok: END__: virtual void UrlLoader::completeJob() - Took 0.0017s The problem is obviously putting url=file://Chiquita.mp3 where it should be something like url=mtp://Chiquita.mp3 because the file is still in the device and not mapped to any local folder. I wanted to know if this happen with other MTP devices as I don't have access to any other ? |

Playing a file direct from an MTP device is not supported. You need to copy it to your collection first. |

Finally got Amarok to play directly from MTP device. The code can be downloaded from here - http://amarok4kde.blogspot.com/2007/02/ ... ce_27.html Right now it only supports doubleclick and maybe returnkey. It uses on-demand caching and providing a proxyUrl to the cached file. |
