I'm using the R16 as MIDI controller [R16 -> a2jmidid (alsa midi)->
(jack midi) ardour3] and audio capture [R16 -> alsa_in (alsa device with
8 input channels) -> ffado jack host].

It seems to work quite well when is running, but there is something not
fine:

 - it takes a long time to the device to appears as an alsa device since
it is detected from the kernel module

 - at least when it is not used (but I think it can occurs even when
streaming) it seems to block ALSA for moments. Meanwhile alsa seems is
unresponsive. Trying to start qjackctl (just open the frontend, not even
starting jack) opened an unresponsive widget. As soon I disconnected the
USB from the R16, the buttons and the control of the widget appeared.

- I was with the above described chain (jack + R16 alsa_in) , and all
the audio devices suddenly hanged. I saw in the R16 the sample rate at
96kHz (when it was -as JACK- at 48kHz)

A dmesg shows this :

Any hint?
