[Simon Fels <simon.busch@xxxxxxxxxxxxx>]

Please note that the kernel subsystem performs various initialization
steps for each HCI controller. Depending on if a controller passes this
it gets up in bluetoothd or not. If a HCI controller is still flagged
with HCI_SETUP or HCI_CONFIG then something is wrong. Even if the
controller turns up in hciconfig that doesn't mean it is usable through
the MGMT kernel interface which is used by bluetoothd today.

If you're debugging this in the kernel look at __hci_init in
net/bluetooth/hci_core.c and verify all HCI commands are sent correctly
and no one gets an error. You can also log those HCI packages send
across the wire with hcidump and analyze the output with wireshark.

Could you also please note which types of BT modules you're using?

Also as you changed the summary it's now pretty unclear to a new person
reading this what the actual problem is ...
