Android moved from USB Mass storage to MTP (Media Transfer Protocol). MTP is a successor of PTP, what is used mostly for picture transfer from digital cameras to pc/laptop.
With USB Mass Storage you'll need to mount the filesystem in your operating system. Since the most filesystems are not very great at concurrent read/write operations, you'd need to umount the filesystem from your digicam, mobile phone or other embedded device. With MTP as protocol (interface) you can access files on the device without the umount/mount orgies.
To use MTP on elive, I'll suggest to install the packages jmtpfs and mtp-tools.
~>>> sudo apt-get install jmtpfs mtp-tools
Connect your mobile phone via USB and run mtp-detect.
In case of a Sony Xperia X, the phone needs to be unlocked (home screen). Else the output is something like:
~ ❯❯❯ mtp-detect libmtp version: 1.1.3 Listing raw device(s) Device 0 (VID=0fce and PID=01e0) is UNKNOWN. Please report this VID/PID and the device model to the libmtp development team Found 1 device(s): 0fce:01e0 @ bus 5, dev 4 [...] usb_clear_halt() on INTERRUPT endpoint: No such device usb_open(): No such file or directory LIBMTP PANIC: Could not init USB on second attempt Unable to open raw device 0 OK.
If the screen got locked after one connect, it's no problem. The unlocked screen shows something like:
~ ❯❯❯ mtp-detect libmtp version: 1.1.3 Listing raw device(s) Device 0 (VID=0fce and PID=01e0) is UNKNOWN. Please report this VID/PID and the device model to the libmtp development team Found 1 device(s): 0fce:01e0 @ bus 5, dev 5 Attempting to connect device(s) Android device detected, assigning default bug flags [.. a lot of lines ..] MTP-specific device properties: Friendly name: Xperia X Synchronization partner: (NULL) Battery level 58 of 100 (58%) libmtp supported (playable) filetypes: Audio Video Interleave Folder Text file HTML file RIFF WAVE file ISO MPEG-1 Audio Layer 3 JPEG file BMP bitmap file [...] Abstract Playlist file XML file Free Lossless Audio Codec (FLAC) OK.
Now you'll need a writable directory. /mnt/tmp doesn't work, so I'm using a directory in home.
>>> mkdir -p ~/android/ >>> jmtpfs ~/android/ [.. now do what you want, using a shell or a filemanager ..] >>> fusermount -u ~/android/ (alternative 'sudo umount /home/[user]/android', see 'mount')
It is also helpful to use the 'Garmin Vivoactive 3 Music', that is using MTP to transfer Music via MTP
Edit: correct two typos
