Question

I have dongle with specific USB UUID (or whatever else it’s called).

I want to set up event when USB device is connected and if the UUID will be right it will unlock protected directory.

I have code how to unlock the directory, but I don’t know how to check device UUID and how to set up event described above.

EDIT: It’s app for GNU/Linux.

You can read the source code for the udev daemon. Or you could just let udev do what it’s already designed to do, and plug your logic in as a udev-triggered hotswap script.
