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. > > To github.com:pavelmachek/ofono.git > > e7b58fdd..1e7e5ce3 mux-v1.19-2 -> mux-v1.19-2 > >=20 > > which creates copy of atchat, so I don't damage existing > > functionality.

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?
