You could try to see if there's any mention of adapters in the kernel boot messages with something like
dmesg|grep -iE "b(lue|t)"
and see if it lists anything interesting.
The other thing, if that doesn't turn up anything, is to look for unknown devices, usually USB devices, so you could check a few listing like
dmesg|grep -i unknown
//or, more directly
Post some findings here when you get them.
