Please make sure you're using ALSA 1.0.9, then add the following at the end of usb/usbquirks.h and recompile the driver: /* -------------------------------------- */ { USB_DEVICE(0x7104, 0x2202), .driver_info = (unsigned long) & (const snd_usb_audio_quirk_t) { .vendor_name = "Miditech", .product_name = "Midistudio-2 (testing)", .ifnum = 0, .type = QUIRK_MIDI_MOTU } }, /* -------------------------------------- */ This will allow the driver to load; it will create two MIDI ports. However, it's quite possible that this will not use the correct protcol to talk with the keyboard. Please show what is output when you're pressing some keys while running "amidi -a -d -p portname" (see "amidi -l" for a list of ports). Regards, Clemens
