I've just picked up a low end bluetooth dongle from SDG (ES-388).
When I plugged it into my MD it would repeatedly cycle through messages saying that it had disabled, removed and added the dongle. It kept doing this until I physically removed the dongle.
here is the error message that I am seeing over and over in the syslog
