Got a used business laptop and found a recessed dongle in it. The original owner says they have no clue, that it’s been in there since they got it. There’s no way a dongle is keeping this thing running, is there? I’ve already swapped the OS, if that matters at all
Update: yubikey! Thank you all for the information, I’m definitely still learning
Oh yeah, you should find lots of tutorials on identifying unknown devices in mint. It probably is a yubikey like others have said; but it would be a good way to teach yourself a useful linux skill if you want to learn it.
Found it! It was listed incredibly verbosely, fully spelling out yubikey and then their website. Thank you!
