How to be notified when a USB device was plugged in?

Question

My system has to auto-mount USB devices; how can I be notified when a USB device is plugged in? Where can I read more about this subject?

I would like to handle this problem via C or a shell script.

And what about specifically "user space" options? I want my own shell script to run A) when a drive becomes available (e.g. auto-mount) and B) when a drive is about to become unavailable (e.g. "unmount" via gvfs or a gui file manager. — user29020, Apr 16 '14 at 14:31

Tip: You can use github.com/mgorny/sw-notify-send for that external program. – lkraav May 19 '11 at 16:18

Don't udev RUN commands run as root? Is there a way to set up a script to run from an unprivileged user space? Thanks. – user29020 Apr 16 '14 at 14:32
