Connect the phone via USB. Go into Settings, About Phone, click on Build Version about 7 times. Then Developer Options becomes available, use that to turn on USB Debugging.

Use `lsusb` to get the phone's code. Example output:

Bus 001 Device 059: ID 04e8:6866 Samsung Electronics Co., Ltd GT-I9...

Create a file or directory `~/.android/adbusb.ini` containing the line "0x04e8" based on the lsusb output above.

As root, drop a file called /etc/udev/rules.d/s4-android.rules containing the following:

SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"

Note that the vendor id is again from the lsusb above.

Run this too (as root):

chmod 644 /etc/udev/rules.d/s4-android.rules

Chef recipe for that file:

file 'udev_rule_s4_android' do
    path '/etc/udev/rules.d/s4-android.rules'
    mode '0644'
    owner 'root'
    group 'root'
end

execute 'udev-restart' do
    command '/etc/init.d/udev restart'
    subscribes :create, 'udev_rule_s4_android', :immediately
    action :nothing
end

Connect the phone in 'PTP' mode:
Connect the phone via USB. Drag down the notifications, click on the 'Connected as...' notification, and set it to PTP or Camera mode.

`adb shell` should now get you a shell on the phone.
