Bluetooth questions

[Stephen Satchell]

Found a workaround that seems to work.  I run these command:

sudo rmmod btusb
sleep 3
sudo modprobe btusb
sleep 5
sudo systemctl restart bluetooth

No powercycle, no system restart necessary so far.  Settings/Bluetooth 
says either "no Bluetooth" or "airplane mode" when things break.

I'll check syslog again when my problem happens.  Are there any other 
logs I need to watch?
