I tried both HCI and PCM but with the same result.
Note that alsa support is not compiled in because the alsa-lib is quite 
old (1.0.16).
As I know the version of alsa-lib and the version of alsa in kernel 
must match.
I'm trying to avoid using alsa (if it is possible) because of the 
previous reasons.
This device is a cash register on buses but now we have to add some 
extra features to it.
The company (who developed the original system) was provided a prebuilt 
firmware, kernel and toolchain.
Unfortunately they don't want to upgrade their working kernel.
This is why I'm trying to get a bluetooth headset working on this 
kernel.

Thanks for the quick reply!
