--------------------------
To answer my own question, things now work with bluez-4.15, 
bluez-gnome-1.8 and the hci_usb module - the btusb module freezes my 
machine on completion of pairing.

Perhaps not a big deal, but I still think bluez-gnome 
(bluetooth-wizard) could be a bit more user friendly when connecting 
to a bt headset (or other device where the use cannot enter a pin) - 
why not give the message "press button on headset" rather than "enter 
PIN 0000"?

Anyway, the sound playback/recording quality seems good.
