| Summary | 0013739: Sync: USB Sync Still Fail on some devices | ||||
| Description | Some devices still trigger MTP Freeze when used with MMW. With one user that have Moto G 4th gen there was a problem MMW not detecting it even Explorer showing the device and was able to copy files on it. After testing and several Mode changes result was that switching from MTP (Player Mode) to File transfer mode made MMW detect the phone. Unfortunately after access and profile creation device was not usable even in Explorer Reset both PC and Device do not change and content on device SDcard can't be modified. To correctly detect the phone Motorola Kies package needed to be installed LOG files of USB fail sync and WiFi successful sync are uploaded on ftp for analyze. NOTE: Apron WiFi Sync Double profile is created as expected due no Actual profile was created over USB Sync on Device and MMW didn't warned user of possible MTP freeze. | ||||

I analyzed the logs from MTP and: - for the "JAN-PCSync OK.LOG" => Just WiFi sync was performed, no USB sync. - for the "JAN-PCSYNC FAIL.LOG" There is MTP failure to create "Music" and "Playlists" folders on the device (because the folders were not visible by Windows), for both the folders the MTP error is 80004005 I would suggest to: 1) verify that the folders aren't somehow "locked" in Android (if they exist at all?) 2) Try to change the sync location to another folders (e.g. Music2, Playlists2) to see whether it solves the issue? |

There must be something wrong in drivers/windows as in File Transfer mode Both explorer and MMW freeze, Folders are accessible for content read but as soon as we try to do anything (eg. folder rename for example or file read) explorer freeze. WiFi sync log was added so that you can confirm that sync works. Folders are there and in use by WiFi Sync, but not for USB connection. I thought that logs would show something as MMW haven't showed MTP error dialog. |

In the "JAN-PCSYNC FAIL.LOG" the sync finished in 14 seconds. The MTP freeze dialog is shown after 2 minutes: 0013280 I guess that standard file copy error dialog was shown in case of the file copy failure? So probably the Music and Playlists folders were created during Wi-Fi sync, but are not accessible using Windows Explorer / MMW ? Resolving as "not fixable", you could try some workarounds from 0012961 , but it is hardly fixable on MMW side. |

Shouldn't MMW try to create Music and Playlists folders and if not successful throw a dialog? |
|
|
Yes, MMW tried them to create them, but there was MTP error 80004005 so it shown the file copy failure, isn't it? |
|
|
Yes, but as it could not create any folders (MMA create test /MediaMonkey/TestDir to check access) MMW should throw MTP error dialog and not File copy dialog which confuses user that complain on MMW sync do not work instead pointing to system issue rather than MMW |
|
|
The MTP freeze dialog is shown only when two minutes MTP freeze is detected (0013280) As for the copy errors, MMW cannot predict in which locations it can create folders and in which it will fail. i.e. the file copy failure is appropriate here. It simply couldn't copy the file because of an MTP error and it correctly reports which files couldn't be copied. If user would try to copy the same file to the same location using Windows Explorer (or WMP) then he would get also just "copy error". In addition in MM (per 0013295) there is the [Help] button pointing to the KB article where user can found more help. So if anything, the KB article could be updated. |
