[Bluez-devel] Acer BT900 Headset profile

[Bluez-devel] Acer BT900 Headset profile

[Carsten Otto]

Hello!

I am quite unsure whether my USB adapter supports everything I need,
but with Class 1 and and higher number in the name (BT900) than I saw
elsewhere I don't think that is a problem.
I was able to setup everything, but can't manage to get more than
noise out of my headset. Whenevery I play sounds (or pipe something
into /dev/dsp1) the noise starts and stops just when the sound is
finished.
Please tell me where the problem could be.
Some information:
- The headset is a Logitech Mobile Bluetooth Headset
- headset info:

I marked the ISOC support for this dongle as broken and so you don't get
any SCO data on the USB bus. So no headset connection possible.

Is there a way to see, like in a device query that isoc is not supported 
on the adapter?

this is again a stupid Broadcom dongle. The descriptors tell that they
support the ISOC endpoints, but it is broken or our they only don't like
our way of dealing with ISOC transfers. Feel free to fix the hci_usb
driver to deal correctly with these dongles.

Marcel

heh... no, I just want to know when to tell people to get another 
adapter. :)

I'll just tell them to stay away from broadcom.
