ok! I got alsa rebuilt and the keyboard recognized,
this is the output
of amidi when I play some notes:

This is the standard USB MIDI protocol from the USB Audio
specification; the driver already knows how to speak this.
Please remove the change from usbquirks.h and apply the patch below
(go to the alsa-driver directory and run "patch -p1 < patchfile");
then everything should work fine.
