(A bit to sidetrack)

To me, it's unclear for devices on USB. When ALSA SoC part supports 
these devices, what is the scenario you assumed? In short, assuming we 
put codes to ALSA SoC part, what is the shape of the corresponding 
devices and links of pairs of endpoints? Additionally, in this case, 
what codes are able to be reused?
