In Ubuntu when I insert a USB stick I get a prompt like:

You have just inserted a medium with digital photos. Choose application to launch.

Here I can set "perform as default action" and this action is now always taken. But I would like to change the action that is now set as default.

How can do this?

Open "System Settings" and navigate to "Details":

From there select "Removable Media" from the left pane. Then you can change what happens when you insert most types of media or turn the prompts off altogether.

More settings can be found under "Other Media".

You can change the default method for handling these events in System Settings -> Details -> Removable Media.
