- MTP with a windows phone on Jessie/KDE
Be aware that many smarphones will only enable MTP while the phone is not locked!*
Graphical User Interface
- launch on attaching your device (e.g., with USB cable)
- interact with an attached device (e.g., by double-clicking the device's icon in the device list).
Install package gvfs-backends
libmtp provides support for MTP devices. Its device support changes with each version of its code, thus you may need a particular version of libmtp (or greater) to support your particular device: e.g., the MotoG phone is not supported directly before libmtp version == 1.1.8 per its maintainers.
Several tools provide a FUSE based file system for mounting MTP devices within the Unix filesystem hierarchy, making it accessible to any program that operates on files and directories. Examples include mtpfs, jMTPFS, go-mtpfs and simple-mtpfs, etc...
install package name=mtp-tools
TODO: document usage, but see below.
Uses FUSE to mount your device's MTP structure into a POSIX filesystem, and fusermount to unmount the device.
install package name=jmtpfs
create <directory> as your mount point: $ mkdir -p <directory>
make sure you have write access to <directory>: $ sudo chown $USER:$USER <directory>
to mount your device: $ jmtpfs <directory/>
On some MTP devices: your screen must be unlocked in order to mount. However, you might get a (spurious) input/output error even if the screen is unlocked.
to unmount your device: $ fusermount -u <directory/>
mtpfs has been orphaned since Squeeze, anyway mtpfs is very similar to jmtpfs, except for the executable name, package name, and package status
install package name=mtpfs
to mount your device: $ mtpfs <directory/>
to unmount your device: $ fusermount -u <directory/>
testing and debugging device connection
Connect your target device (e.g., Android phone) to your Debian host (e.g., laptop) via USB cable, and unlock the target device. Relatively quickly, you should see the following:
Your Debian host's desktop should open a file browser (e.g., a nautilus window) showing the browsable contents of a location. If the location is mounted in your filespace, you should not need to read further from this article. Alternatively, the location will be shown with a URI beginning with mtp://, which will not be mounted, but can be manipulated via the usual means provided by your file browser (including copying and deleting files). If you wish to actually mount that location (i.e., your target device), read on.
- The target device may also show some GUI, such as choosing the connection mode. If so, choose mode=MTP.
If neither of those occur, you should
- Check your connection, e.g., the USB cable. If fixing that does not make your target device browseable as described above, then ...
Check which version of libmtp and associated packages you have installed on your Debian host: see following section=device statuses. Install them if not already done. You will minimally need to have the executable mtp-detect in your path.
Run mtp-detect from your host with your target device attached.
If you see results like
$ sudo mtp-detect Unable to open ~/.mtpz-data for reading, MTPZ disabled. libmtp version: 1.1.8 Listing raw device(s) No raw devices found.
... stop and seek help elsewhere. If you see results like
$ sudo mtp-detect Unable to open ~/.mtpz-data for reading, MTPZ disabled. libmtp version: 1.1.8 Listing raw device(s) Device 0 (VID=<something/> and PID=<something else/>) is UNKNOWN. Please report this VID/PID and the device model to the libmtp development team Found 1 device(s):<remaining text omitted for this documentation/>
If you see results like
$ mtp-detect Unable to open ~/.mtpz-data for reading, MTPZ disabled. libmtp version: 1.1.8 Listing raw device(s) Device 0 <... remaining text omitted for this documentation, ending with/> OK.
then you should be able to mount the target device onto your host's filespace as discussed in the following example.
Example: laptop, MotoG, USB, libmtp, jmtpfs
I have a (working) 1st-generation Motorola MotoG running Android version=4.4.4 that I wish to mount on a Debian laptop. Latter has

With no MTP devices connected to the laptop, I see (from the laptop)

I then unlocked the MotoG's screen and connected it to the laptop with a USB cable.
Immediately upon connecting, a nautilus window opened on the laptop showing the browsable contents of location=mtp://[usb:001,040]/ with device name=XT1028. I can also see (from the laptop)

I can then mount the MotoG's storage with
$ jmtpfs ~/Android_transfer/ Unable to open ~/.mtpz-data for reading, MTPZ disabled. Device 0 (VID=22b8 and PID=2e82) is a Motorola Moto G (ID2).

... and unmount the MotoG's storage with
$ fusermount -u /home/me/Android_transfer $ ls -al ~/Android_transfer/Internal\ storage/ ls: cannot access /home/me/Android_transfer/Internal storage/: No such file or directory
failed jmtpfs mount
I initially tried to mount the MotoG using sudo. Don't do that! You'll get results like
$ sudo jmtpfs ~/Android_transfer/ Unable to open ~/.mtpz-data for reading, MTPZ disabled. Device 0 (VID=22b8 and PID=2e82) is a Motorola Moto G (ID2). ignoring libusb_claim_interface() = -6PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device Android device detected, assigning default bug flags $ ls -al ~/Android_transfer/ ls: cannot access /home/me/Android_transfer/: Permission denied $ sudo ls -al ~/Android_transfer/ ls: cannot access /home/me/Android_transfer/: Permission denied $ sudo fusermount -u /home/me/Android_transfer
Remember: MTP filesystems are implemented as FUSE, which means Filesystem in your Userspace.
copy files off your smarphone with mtp-getfile
First install the mtp-tools package:
$ sudo apt-get install mtp-tools
Then get the list of available files:
$ mtp-files > file_list.txt
file_list.txt will now contain entries like this:
File ID: 81 Filename: WP_20161029_16_26_49_Pro.jpg File size 936160 (0x00000000000E48E0) bytes Parent ID: 12 Storage ID: 0x00010001 Filetype: JPEG file
where "Parent ID" is something like the folder where the file resides on the smartphone. So you'll want to do something like this to get that particular file:
mkdir "12" mtp-getfile "81" "12/WP_20161029_16_26_49_Pro.jpg"
Yes, the mkdir "12" and the 12 from the Parent ID in the local file is important.
MTP with a windows phone on Jessie/KDE
This has been tested with a Lumia 530 with Windows Phone 8.1
- First, to have the Lumia correctly detected in KDE, you have to update your libmtp packages to the ones in "debian backports". Right now, in jessie we have libmtp 1.1.8 which is not sufficient to detect the Lumia. in Backports you have 1.1.10 which detects the phone correctly
Then, to be able to browse the phone in KDE, you need to install "kio-mtp" package. In jessie it is version 0.75+git20140304 . But with the version in jessie you will face the following issue in Dolphin "mtp:udi=/org/kde/solid/udev/sys/... does not exist". To get that fixed, you need to recompile yourself the package with the patch from https://bugs.kde.org/show_bug.cgi?id=325335. I backported that patch and sent it back to that kde bugreport in case someone is interested.
