Hi all,

I am using a 2.6.8.1 kernel and successfully communicate with my
Nokia 6230. Today, I got a Jabra BT 250 headset, which also works
fine.

However, I cannot make bluez see it. What's more, if I pair phone
and headset (which also works), then `hcitool scan` does not find
the phone anymore. I have to delete the pairing between the headset
and the phone to be able to communicate with the phone again.

What's going on? Can the phone only pair with one other device? Or
is the problem elsewhere?

Also, I can't figure out how to pair the computer with the headset
(assuming that phone and headset are not paired). I set the voice
type to 0x0040 (not sure why, but I saw it on the Internet; it also
does not work with 0x0060, the default) and I added Audio and
Telephony to the dongle's classes; I even added the HF SDP service.
But when I execute `hcitool scan`, only the phone shows up.

Here is hciconfig -a hci:
