I have a problem using Bluetooth with a Hama BT1000 Headset.
I installed th elatest Bluez Version (2.17) and the snd-bt-sco driver
via cvs. I followed the instructions on how to install the bt-sco module
and userland program and everything worked fine.
I already searched the archives, but found nothing helpful.

The first problem I encountered was, that I am not able to pair the HS
with my computer. I put the HS in pairing mode and run the command:

	btsco <headset> -v

Then I get the following:

	btsco v0.4b
	Device is 1:0
	Error: Failed to connect to SDP server: Invalid exchange
	Assuming channel 2

	Voice setting: 0x0060
	Can't connect RFCOMM channel: Invalid exchange

However, when I ignore the fact, that I haven't paired yet I can still connect the HS
just as I would have done and I am able to start xmms playback. However, I don't
hear a sound on the HS and xmms freezes after the 1 second of playback. Although
the Status LED on the HS indicates data transfer and I can change the volume. This
is what the userland program says:

	:~$ btsco 00:0B:2E:06:15:74 -v
	btsco v0.4b
	Device is 1:0
	Voice setting: 0x0060
	RFCOMM channel 6 connected
	speaker volume: 15 mic volume: 15
	i/o needed: connecting sco...
	connected SCO channel
	Done setting sco fd
	recieved AT+VGS=15
	Sending up speaker change 15
	recieved AT+VGS=14
	Sending up speaker change 14
	recieved AT+VGS=14
	speaker volume: 15 mic volume: 15
	driver is not in use
	disconnected SCO channel
	speaker volume: 15 mic volume: 15
	i/o needed: connecting sco...
	Can't connect SCO audio channel
	: Connection timed out
	speaker volume: 15 mic volume: 15
	RFCOMM channel lost

Don't really now, what is happening. But it somehow seems, that the audio-data never reaches the headset
(but that is simply a guess from someone not knowing whats going on).A yes, I get the same, when I am
doing an 'aplay' like mentioned in the README.

Here are some additional infos:

One last thing. The USB Bluetooth Dongle(Class II) is working. I can share data with my
mobile phone just fine.

Thanks for your help, Tobias Lang
