with CM10 it does not work at all , mtp-detect gives

Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
   Found 1 device(s):

Bug description:
  Android 4 will not support anymore usb mass-storage protocol. However,
  there is an easy way to access the files on such devices for advanced
  users using mtp-tools and adjusted udev-rules:
  http://www.omgubuntu.co.uk/2011/12/how-to-connect-your-android-ice-
  cream-sandwich-phone-to-ubuntu-for-file-access/ . Ubuntu Precise
  Pangolin (12.04) should be prepared for Android ICS devices and grant
  easy access to music and pictures and other files to all users.
