Try adding the following entry to sound/usb/quirks-table.h or usbquirks.h: { /* has ID 0x0110 when not in Advanced Driver mode */ USB_DEVICE_VENDOR_SPEC(0x0582, 0x010f), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { /* .vendor_name = "Roland", */ /* .product_name = "A-PRO", */ .ifnum = 1, .type = QUIRK_MIDI_FIXED_ENDPOINT, .data = & (const struct snd_usb_midi_endpoint_info) { .out_cables = 0x0003, .in_cables = 0x0007 } } }, Regards, Clemens _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
