I have problems with the Broadcom BCM2045 connecting to a Sony-Ericcson
headset (HBH-610a). It connects but it then immediately disconnects.
This does not occur when using a Kensington USB bluetooth dongle so I
know that connecting to the headset is possible.

Is there something else I need to do to get this to work? Any help would
be appreciated.
