Ahhh.  See.  Shows what I know about the details of B/T.  I thought one
adapter == one piconet.

Hrm.  I guess I will have to play with that a bit.

OK.  So as far as the link policy that keeps the adapter as master,
after having rebooted this machine today I found the following:

$ hcitool con
Connections:
$ hciconfig hci0 lm
hci0:	Type: BR/EDR  Bus: USB
	BD Address: 00:02:72:1E:E0:12  ACL MTU: 1021:7  SCO MTU: 64:1
	Link mode: SLAVE ACCEPT

So that means that the adapter will want to be the slave in all
connections, is that right?

I should change the above slave to master as such:

$ sudo hciconfig hci0 lm master
$ hciconfig hci0 lm
hci0:	Type: BR/EDR  Bus: USB
	BD Address: 00:02:72:1E:E0:12  ACL MTU: 1021:7  SCO MTU: 64:1
	Link mode: MASTER

Is that correct?  Do I want to enable that "ACCEPT" also?

Once I do that, for my mouse at least, do I want to press the "Connect"
button on the mouse or use the Connect option for the mouse in the
bluetooth-applet?
