How to mount Moto G on Ubuntu using MTP

Ha funcionat correctametn aquest tutorial:

En el tutorial es comenta que aquesta opció va molt lenta, i no és el que jo he trobat. La transferència de fitxers va a una velocitat més que raonable.

Moto G is an Android smartphone that does not have a microSD slot. So, the storage of the smartphone cannot be extended. If you want to transfer files between your Ubuntu computer and the Moto G, there are 3 possible ways to do that: FTP over wireless, PTP over USB and MTP over USB.

If your Ubuntu computer has wireless, I highly recommend using FTP over wireless. It is convenient (no wires!), offers good transfer speed and the entire /sdcard contents are available for read and write.

If your Ubuntu computer does not have wireless, then your next option is to use a micro-USB-to-USB cable. The choices here are PTP and MTP. You can enable and switch between the two after you connect Moto G to your computer using a USB cable. If you enable PTP, then Moto G is automatically mounted as a partition in Nautilus. However, you will only be able to see the /sdcard/DCIM and /sdcard/Pictures directories. If you are transferring photos, then this option offers good transfer speed.

If your Ubuntu computer does not have wireless and you still want to read and write to the contents of /sdcard then the option left to you is MTP. Note that with MTP, Moto G takes a really long time to mount and the transfer speeds are really really low. It can take ages to transfer even a small file. You have been warned! :-)

There are many solutions offered online to mount the contents of /sdcard using MTP. This solution is the only one that worked for me:

Install the MTP packages:

$ sudo apt-get install mtp-tools mtpfs

Connect Moto G using a USB cable to your computer. Make sure MTP is selected, and not PTP.

Find out the vendor ID and product ID of Moto G using mtp-detect. For my smartphone I got:

$ sudo mtp-detect
Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.3

Listing raw device(s)
Device 0 (VID=22b8 and PID=2e82) is UNKNOWN.
Please report this VID/PID and the device model to the libmtp development team
   Found 1 device(s):
   22b8:2e82 @ bus 1, dev 12
Attempting to connect device(s)
Android device detected, assigning default bug flags

You need to press Ctrl+C to stop the command. For the Moto G, you can see that the vendor ID is 22b8 and product ID is 2e82.

Open a new file /etc/udev/rules.d/51-android.rules using sudo and add this line:

SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", ATTR{idProduct}=="2e82", MODE="0666"

Restart the USB service and create a directory to mount the Moto G:

$ sudo service udev restart
$ sudo mkdir /media/motog
$ sudo chmod a+rwx /media/motog
$ sudo adduser your-user-name fuse

Open the /etc/fuse.conf file as sudo and uncomment the line for user_allow_other

Restart your computer. Connect back the Moto G to the computer.

You can now mount the /sdcard of your Moto G using this command:

$ mtpfs -o allow_other /media/motog/

Note that the mounting operation is slow and might take about a minute. (s'ha d'esperar una mica, per exemple fins que pugui fer cd /media a la carpeta per la consola).

You can find all the directories and files in /sdcard of Moto G in /media/motog. You can read and write to these directories.

To unmount use this command:

$ fusermount -u /media/motog/

FTP over wireless

És la millor solució. A l'android instal.lem un servidor de FTP com Wifi FTP, i al Ubuntu instal.lo un client com gftp.
