The USB Device trigger executes a macro when a USB Device is attached or detached.

Caution: The USB Device name may be quite different to what you might think the device is called.

If your text focus is in the device name field, Keyboard Maestro will detect and fill in the name of any device that is attached.

A great use for this trigger is to launch your scanner software when you turn on your scanner, and quit it when you turn off your scanner.
