Re: [Bluez-devel] a2dp, sco and kernel version

[Manuel Naranjo <naranjo.manuel@gmail.com>]

I want to help, just tell me what you need and I get it to all for you.
I work for the company that builds the USB dongle [1], and I'm using the 
hifi headset we sell. So I have plenty access to almost every hardware 
detail. So please let me know what you need, logs, etc, and I get it.
Thanks,
Manuel
