ifconfig? I thought I should get /dev/ttyUSB0..3?

Anyway, that does not seem to work. Something is detected now:

[   10.819549] ALSA device list:

But qcserial driver does not bind to that. If I attempt to force it:

I don't get anything useful. Do I need to boot android before booting
Linux or something? How does your lsusb look like?

Thanks,
