Update: Found out this is actually a feature if a device PIN is not set ([source](https://docs.crp.to/duousersguide.html#set-up-a-slot-advanced)).

> My new OnlyKey Duo seems to stay unlocked all the time, even after I remove it from the USB port and plug it in again, or after I plug it into another device. This can’t be the expected behaviour, right? (My non-Duo OnlyKey certainly doesn’t behave this way.)
