[gentoo-user] Bluetooth and hciconfig

[Mick]

A recent post had me investigating this.  I'm on net-wireless/bluez-5.43-r1 
which thankfully provides the hciconfig utility.  I have used hciconfig for 
years now to enable the bluetooth adapter on my laptop.

Starting /etc/init.d/bluetooth does not enable the adapter itself.  Setting

AutoEnable = true

causes an error in the logs:
============================

============================

The adapter remains disabled:

# hciconfig 
hci0:	Type: Primary  Bus: USB
	BD Address: 90:4C:E5:FA:F2:A8  ACL MTU: 1021:8  SCO MTU: 64:8
	DOWN 
	RX bytes:1058 acl:0 sco:0 events:52 errors:0
	TX bytes:951 acl:0 sco:0 commands:52 errors:0


Enabling it manually with hciconfig works as always had:

# hciconfig hci0 up piscan
# hciconfig 
hci0:	Type: Primary  Bus: USB
	BD Address: 90:4C:E5:FA:F2:A8  ACL MTU: 1021:8  SCO MTU: 64:8
	UP RUNNING PSCAN ISCAN 
	RX bytes:1599 acl:0 sco:0 events:80 errors:0
	TX bytes:1559 acl:0 sco:0 commands:80 errors:0

So, what's the solution if hciconfig et al are not installed with future 
versions of bluez and the AutoEnable option does not seem to take?
