Public bug reported:
I configured 4 bluetooth headsets as audio sinks on my pc and they work
as they should.
Anyway, bluetoothd (version 4.101-0ubuntu13.1 on Ubuntu 14.04.2 LTS)
tries to connect to all these headsets during startup, delaying boot by
20+ seconds.
Feb 21 17:22:33 pc bluetoothd[607]: Adapter /org/bluez/607/hci0 has been enabled
Feb 21 17:22:40 pc bluetoothd[607]: Host is down (112)
Feb 21 17:22:40 pc bluetoothd[607]: discovery failed
Feb 21 17:22:45 pc bluetoothd[607]: Host is down (112)
Feb 21 17:22:45 pc bluetoothd[607]: discovery failed
Feb 21 17:22:50 pc bluetoothd[607]: Host is down (112)
Feb 21 17:22:50 pc bluetoothd[607]: discovery failed
Feb 21 17:22:56 pc bluetoothd[607]: Host is down (112)
Feb 21 17:22:56 pc bluetoothd[607]: discovery failed
If I don't connect the usb bt adapter, the boot process is fast. If I
connect it after the system has booted, bluetoothd does not try to
enumerate the headsets, but as soon as I try to use one of them, it
connects and works, so I don't understand why it should delay everything
in the other case.
Feb 21 18:12:08 pc bluetoothd[546]: Adapter /org/bluez/546/hci0 has been enabled
Feb 21 18:13:28 pc kernel: [ 120.038610] input: 00:18:6B:66:24:1E as
/devices/virtual/input/input11
There should be maybe an option to disable discovery during bluetoothd
startup (I couldn't find one).
