I'm on a 2011 8,3 MacBook Pro running Ubuntu 11.10 amd64.
I've been using the Bluetooth card in my machine perfectly for a long time. All of sudden, for no apparent reason, the Bluetooth device is gone.
hcitool dev shows no devices at all.
What on earth happened? How can I find my Bluetooth card and get it working again? The only thing I did was install
b43 from a compat-wireless, as I had to compile it myself. Is there something I did wrong there? How can I tell what the problem is and fix it?
