I got it! For getting the keyboard recognized I erased _VENDOR_SPEC from
the definition in usbquirks.h and left it like this:
{
USB_DEVICE(0x7104, 0x2202),
.driver_info = (unsigned long) & (const snd_usb_audio_quirk_t) {
.vendor_name = "Miditech",
.product_name = "MidiStudio-2",
.ifnum = 0,
.type = QUIRK_MIDI_MIDITECH
}
},
instead of:
{
USB_DEVICE_VENDOR_SPEC(0x7104, 0x2202),
.driver_info = (unsigned long) & (const snd_usb_audio_quirk_t) {
.vendor_name = "Miditech",
.product_name = "MidiStudio-2",
.ifnum = 0,
.type = QUIRK_MIDI_MIDITECH
}
},
It creates two ports:
hw:2,0,0 MidiStudio-2 MIDI 1
hw:2,0,1 MidiStudio-2 MIDI 2
The second one is the one with the Midi stream from the keyboard. What
would be the first one?
Thank you a lot!!!! Right now I'm playing ZynAddSubFX through Jack using
my Midistudio-2 USB.

ok! I got alsa rebuilt and the keyboard
recognized, this is the output
of amidi when I play some notes:
[root@localhost ~]# amidi -a -d -p hw:2,0,1
09
90 3C 5F
09
90 3C 00
09
90 3B 5D
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.
