I'm getting random 3905 Disabled Bluetooth Dongle messages.
The dongle, an MSI 3X Mega Net Star Key has on occasion shutdown.
Other times the application it is being used with (i.e. wiimote) just requires reactivation.
It's nice having the indicator lamp telling me if it's dead (shutdown) or just off-line.
Just thought I'd let you know.
p.s. Booted system up this afternoon (Apr. 12) and got 5392 Disabled message -device is offline.
Rebooted -didn't see message but device down.
F8 says not starting device 70 Bluetooth Dongle - it is already running.
Later I saw...
"[ 311.092232] hci_cmd_task: hci0 command tx timeout" messages being generated every 36/37 seconds apart.
I pulled the dongle out...
