[Richard Huddie]

ENVIRONMENT:
Device: ubuntu-rtm/14.09 build 1
Desktop: Ubuntu 14.04/14.10

SUMMARY:
Unknown libmtp error when copying content from internal storage to SD card using MTP.

This might be the case for someone who has a new memory card and they want to copy/move content to it from device's internal storage.

STEPS:
1) Connect Ubuntu device to Ubuntu host PC over USB
2) Attempt to copy/move some music content directly from device's internal storage to device's SD card using MTP

EXPECTED RESULT:
The content should be copied/moved successfully.

ACTUAL RESULT:
The following error is displayed on desktop:
"libmtp error: Unknown error".

[Richard Huddie (rhuddie)]

Note that the same error occurs when you try and move content from within the same drive. E.g. moving a file from one folder to another on the same storage drive.

Status changed to 'Confirmed' because the bug affects multiple users.

I had to install mtpfs on the PC (and enable USB debuging in the phone).
Copying from mtp device to same partition or another inside fails with libmtp error : unknown error
Moving inside the same partition works, but only from the left USB port.
Moving from one partition to the other works (still left USB port) this way : move original folders/files to the PC disk, then from the PC disk to the 2nd partition.

Neither mtpfs nor jmtpfs are useful, nor help (uninstalled).

It seems I can copy/move files, but not folders :

Erreur lors de la copie du fichier dans « mtp://[usb:003,049]/M%C3%A9moire%20de%20stockage%20interne/Music ».
This error was when I copied and empty folder. Although speaking of file instead of a dir.
There may be or not an error : the french string is /Mémoire de stockage interne/Music.
Although copy succeeds when catching files without a parent directory.
