On the "determine if anything suspicious is happening" front, you can configure Wireshark to capture USB packets and show you what is going over the wire.

Oh nice! I've used Wireshark for TCP / UDP captures before but that's about it.

Maybe I can use a raspberry pi as burner device and check it out.

A pi zero would do the job and only risk about $5 to find out what's on the stick.

Nice idea. Start a service where people mail unknown USB devices to you and you email back a disk image.

That sounds really interesting. You should post later if you go through with your plan!
