btsco: Not working...but almost

Okay, I'm in the situation I've seen reportet a few times on the List:

Everything seems as if it were working, but I can't actually hear any sound sent to the Headset. I suspect it's the unsupported Bluetooth adapter in my laptop, which ist, unfortunately, Broadcom-based.

Any chance to get these supported? Using an additional USB Bluetooth stick when I have a built-in adapter seems stupid.

Anyway, here's my configuration (I'm going by the bulletpoints on the bluetooth-alsa page):

Hub: Don't know. It's internal, as I said. They might have wired it up in a weird way. I see the Bluetooth dongle as "Bus 4 Device 2".

Headset: Jabra BT500
Adapter: The one that comes with an IBM T43p, Broadcom-based

I hope I can somehow get this configuration to work. Otherwise, I'd have to either send back the headset or get a CSR adapter. Both would annoy me, obviously. Thanks for any help you can offer.

I looked into finding technical docs from another vendor for the same problem (integrated bluetooth adapter not csr) but didn't get very far. If you can find technical docs, maybe it's not that bad to add support. I don't know, but without docs the point is moot.

Maybe you don't like the usb adapter for the same reason I don't. I really hated the idea of putting a usb dongle on my laptop that could get knocked off or forgotten when I was packing up. So the socketcom cf adapter was attractive since it doesn't protrude. I don't have it any more and I can't remember offhand if I tried sco in linux. Surely someone on the list could tell us.

The good news: I just went and bought an additional BT dongle, nice and CSR-based:

The bad news: Suddenly things work even less than before. I must have badly fucked up my configuration along the way. I can't even talk to the Headset now. hcitool scan works, nothing else, not even hcitool info:

sp8472@Maik-2013:~$ sudo /etc/init.d/bluez-utils stop

Any idea how to get things working now?

Hi Maik,

what kind of dongle is this? I like to get one with a BlueCore4-ROM chip for myself.

Regards

Marcel

Get my headset to work with my internal bluetooth adapter and you can have it. ;-)

No, seriously. You could. But I guess that's not gonna happen anytime soon, without specs from Broadcom...

...and after a little more fiddling, the headset now works as expected. Buttons and everything, tested against Skype. Thanks for writing a driver for this. :-)
