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"
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 - a simple tool that realises reflexes on your computer.

For those without
udisks, you can also useumount /dev/sdb1to unmount the drive andeject /dev/sdbto detach it (it will no longer show up on the sidebar of the file browser). This can also be done by UUID instead (umount /dev/disk/by-uuid/<UUID>), in case having other USB devices plugged in changes the device name (i.e./dev/sdbbecomes/dev/sdc) – Brandon Miller Sep 20 '20 at 4:35
