(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?
