[Bug 1092621] Re: Ubuntu 12.10 does not support Google Nexus 4 phone in MTP mode

There was recently a change to the adb tool.  It now does
authentication; the user is prompted to "allow" a new computer when the
phone is connected to it.  The old adb is not compatible.

This change is probably why it fails, even though MTP on the Samsung
Galaxy Nexus previously worked.

I used the new adb (with the authentication) to manually push files.
That worked fine.  Trying the other forum posts (like changing the udev
rules) did not work for me.

It was very aggravating to get the cool new phone (Nexus 4) and then not
be able to transfer files to it.

Title:
  Ubuntu 12.10 does not support Google Nexus 4 phone in MTP mode

Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  I have just bought a Google Nexus 4 phone. The device supports two
  transfer modes: MTP and PTP. MTP is the default for this phone.

  If MTP is selected (the default), the device is not detected. If I connect the device to a PC running Windows 7, a range of directories are accessible, including Music, Downloads, Pictures etc. This was the behaviour I expected to occur on Ubuntu.
  If I select PTP, the device is detected as a camera by Ubuntu. The DCIM and Pictures directories are accessible.

  Ubuntu appears therefore not to support the Nexus 4 in MTP mode. I
  will append the output of lsusb and mtp-detect.
