Do you have an idea why that causes problems with usb data connection?
I created a script to disable charging -- and that works. I also found
out cable about 5cm long. Not nice to use, but works significantly
better w.r.t. charging.

As I said, still ton of work to do :-(.

Ofono does not normally touch ALSA, so I'd prefer not to do it from
there.
But I might be confused. I recall some audio patches were needed for
basic phone calls (setting up mixers to connect gsm<->audio), but
those worked before gsmux support was enabled. (Maybe some hardcoded
commands were needed to be sent to gsmmux somewhere).
I assume neither gsmmux audio parts nor mixer parts are available in
-next at the moment?
Best regards,
Pavel
