Can't explore files on my Sony Xperia U using my Ubuntu 12.10 laptop I previously used Ubuntu 12.04. When I connected my phone (Sony Xperia U) in MTP mode, I would be able to see it in Nautilus as a "SEMC HSUSB device" and browse files, copy files, and so on.

Now, I have a new laptop and I've installed Ubuntu 12.10 on it. My device is not recognised any more by Nautilus - I can see that the OS recognises it by seeing the entries that appear in /var/log/syslog - but the phone does not get mounted and I can't think of any way to access the files on the phone and put new files there except the terribly slow Bluetooth.

Has anyone else faced such an issue? Can you help?
I have found the simplest method, with both my Samsung Galaxy Tab2 7.0 tablet and Galaxy S3 Mini smartphone, is to use SSHDroid (on the Android device) to provide SSH server.

Then I simply connect from Nautilus using SSH, over WiFi. This is plenty fast and I can bookmark the links for re-use (provided the IP address stays static). After first use, I simply set a static IP on my router for those MAC addresses.

I have also used a terminal, for an SSH command line session to the devices. This also just uses the SSHDroid service.
