> this be as easy as turning off autorun

What does autorun have to do with a mouse or keyboard device? The problem with USB is that you don't know if it is a "mass storage device" or any of the other kinds of devices that can start interfacing with your computer.

If it is an (automated) keyboard device (HID), it will immediately start "typing" which means it can open a terminal window and start executing things.
