hi,
notice that sometimes the bluez stack runs into a state where I cannot
connect rfcomm channels any more etc. To get into a sane mode of operatio=
n,
pulling and plugging the bt dongle helps normally.

As we build a system that will be hidden behind a wall, I need a software=
-
only solution to this. I tried to stop the bluetooth services as well as =
hotplug,
unload any dangling modules, then start hotplug and bluetooth services ag=
ain and
I send a hci_reset to the device.

Unfortunately, this does not resolve my issues, but I get lots of submit =
failures:

etc., as well as loads of other mysterious happenings.

Is there a proper way to reset this device other than soldering a paralle=
l-port controlled
power switch?
