Hi, I am up to date on the latest update, bought the USB 4.0 dongle that Ian had on a link on a different thread here. BUT, i plugged the USB in and it won't pair because it's expecting a pairing code. I feel that the USB that came might be an old version because raspberry pi is not on the list of compatibility on the package it came in. Is this right? anyone else experience difficulty with the USB dongle thing?
