I want to stop a USB device from automounting in Ubuntu 13.04. For example, when I connect my iPhone 5 to my desktop I am consistently prompted for what I want to do (whether or not I want to erase the "iPod" connected to my machine, etc). Since I don't use the computer as anything more than a way to charge the device, is there a way to prevent the device from mounting and still allow the device to draw current from the machine?

Using the terminal and gedit

First find the ID for your device from a terminal using lsusb when your device is connected (eg 0951:1692). Also you should to find what is the name of your device with lsblk. Let say the name is /dev/sdb1.

Create a new script, let say unmount.sh in /lib/udev with sudo -H gedit /lib/udev/unmount.sh and put next lines inside:

#!/bin/bash

udisks --unmount /dev/sdb1
udisks --detach /dev/sdb

Save the file, close it and make it executable with:

chmod +x /lib/udev/unmount.sh

Now, you must to make a new rule file in /etc/udev/rules.d/ with sudo -H gedit /etc/udev/rules.d/100-unmount-iphone.rulesand put a new rule in there like this:

ACTION=="add", ATTRS{idVendor}=="0951", ATTRS{idProduct}=="1692", RUN+="/lib/udev/unmount.sh"

enter image description here enter image description here enter image description here

To reload udev rules without restart, use next command:

sudo udevadm control --reload-rules

Using Cuttlefish

Or, another way is to install and use Cuttlefish Install comixcursors-lefthanded - a simple tool that realises reflexes on your computer.

Oh well, looks like Cuttlefish is no longer available –  Antony Sep 25 at 2:29

To control which programs automatically start when you plug in a device, go to

System-Settings - Details - Removable Media
