alsa-project/alsa-lib issue #24 was edited from symdeb:

Since MIDI 2.0 only support USB and not over DIN (for now), will MIDI 2.0 need a new or updated OS class driver for the 32/64 bit universal packet interface and device descriptor for devices ? Page 16 of the USB MIDI class driver spec defines support for 1,2 or 3 bytes transfers only, How will this have to be implemented by MIDI USB device manufacturers and well as on the Linux OSes side ?  How will this impact Linux ALSA ? Would the first byte of the message with b7=0 not confuse the driver of running status ?
