After upgrading from 12.10 to 13.04 I am having issues with connecting my Google Nexus to my Ubuntu machine.

I have found this script somewhere on the Internet but it does not seem to work now :

#!/bin/bash



if [ `lsusb |grep Google |wc -l` == 0 ]; then

    echo "plug in the device"

    exit 1

fi



if [ `dpkg -l mtpfs |wc -l` == "0" ]; then

    sudo apt-get update && sudo apt-get install mtpfs

fi



rules_file=/etc/udev/rules.d/60-android.rules

if [ ! -f $rules_file ]; then

    vp=`lsusb|grep Google|cut -d " " -f 6`

    vendor=`echo $vp | cut -d ':' -f 1`

    product=`echo $vp | cut -d ':' -f 2`

    rule="SUBSYSTEM=="usb", ATTR{idVendor}=="$vendor", ATTR{idProduct}=="$product", MODE="0600", GROUP="plugdev" OWNER="$USER""

    sudo bash -c "echo $rule > $rules_file"

fi  



mount_point=/media/nexus

if [ ! -d $mount_point ]; then

    sudo mkdir $mount_point

    sudo chmod 775 $mount_point

fi  

sudo mtpfs -o allow_other $mount_point

After launching it I get :
