And as far as I know it has SCO mapped to PCM and not HCI, so this is the reason, why your setup is not working. Check mail list archive how to change this, or if it is even possible on this old chip. PCMCIA version does not have this problem. br, Mitja On Thu, 23 Mar 2006, Tom K wrote: > First post here, not a developer, but I'm posting here as advised on the > bluetooth-alsa site. > > I have a 3Com 3CREB96 USB dongle and a SonyEricsson HBH-602 headset.
