Re: [Bluez-devel] Bluetooth headset problems.

Hi,

I believe that there is a problem with the hci-usb driver. I performed some
brief investigations which I posted earlier to this mailing list.

Are you using a USB device? I've used the same code and Bluetooth headset
with a PC card Bluetooth adaptor and everything worked fine.

Both Bluetooth devices use the CSR chipset, but the UART one using the BCSP
protocol works whereas the USB one misses half the data packets, as you
suggest.

My earlier message was posted on 20th June, entitled "SCO problem with USB
devices" - I'd be interested to see if your problem looks the same. I think
it possibly is, from what you've posted.

I haven't yet got around to investigating the problem with the USB stack -
but I have the same problem, if it helps! If you are in a rush, then PC card
devices seem to work at the moment...

Regards,

Colin

I have made some progress. I can now record audio from the headset 
without it loosing any samples. I.e. I can record 8 bit PCM at 8000hz 
and it sounds fine. Before it was loosing samples and recording at more 
like 4000hz.
Once I get playback to work, I will post a patch to this list.
Cheers
James
