SYSFS was deprecated in the recent versions of udev.

Your file should only have lines like this:

SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"

where 0bb4 is the vendor id.

You can get the vendor id for your phone through the terminal. Run 'lsusb' on the commmand line and find the line with your device.

For example, on my case: Bus 004 Device 004: ID 18d1:4e22 Google Inc. Nexus S (debug)

So the vender id is 18d1.

And the above line becomes:

SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev"
