you want MTP support on Ubuntu, try this:
- Connect Xperia S to an USB2 port.
- Use the "lsusb" command to list your devices in a terminal One of the lines should look like this: Code:
Bus 002 Device 012: ID 0fce:5169 Sony Ericsson Mobile Communications AB
- Note your vendor- and product id. Usually this is "0fce" for the vendor and "5169" for the product id. If you have USB debugging disabled, product id will be "0169".
- unplug your phone
- read this thread: Install the newest Version of "libmtp" and copy the 69-libmtp.rules file to /etc/udev/rules.d as described
- Edit: This step may not be necessary for you! Xperia S support is implementet in the libmtp-1.1.3. release. If you use the newest version from skip this and go to step 7.type following to edit the copied file as root: Add the following text somewhere around the sony ericsson devices that are in this file. You can find them by searching for "0fce". Remember to set the correct vendor and product id:Code:
sudo gedit /etc/udev/rules.d/69-libmtp.rules
Code:# Sony Xperia SATTR{idVendor}=="0fce", ATTR{idProduct}=="5169", SYMLINK+="libmtp-%k", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"ATTR{idVendor}=="0fce", ATTR{idProduct}=="0169", SYMLINK+="libmtp-%k", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1" - reboot, or use to actualise.Code:
sudo udevadm control --reload-rules
- Plug in your device to a USB2 port, it will mount automatically. Use nautlius to copy files around.
