[SOLVED] These two identical things I found on a dusty ol' shelf in a classroom
Pencil for scale. Circuit board, 1 USB plug that lights up an LED when you plug it in. Windows doesn't recognize it as a device. Two little metal leg things with "feet".
dood. don't plug an unknown foreign device in your PC. especially not a Windows PC. It's a common attack vector to leave devices with malware at a site (usually USB dongles, smart watches, chargers or even cables*) you want to hack, so people plug them in where you can't.
