Anyway, you need the module snd-usb-audio for it, because this 
module handles MIDI as well as audio over USB. On ALSA, 
there's no singular dedicated usb-midi-module to only handle 
MIDI data (AFAIK in older ALSA versions usb audio and midi 
have been two different modules, but this has changed).

The file has to be created, it does not exist per default.

I have two USB cards and do not use an /etc/asoundrc
