If you know how to compile a kernel, add the following entry anywhere in sound/usb/quirks-table.h: { USB_DEVICE(0x0582, 0x012a), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { /* .vendor_name = "Roland", */ /* .product_name = "UM-ONE", */ .ifnum = 0, .type = QUIRK_MIDI_FIXED_ENDPOINT, .data = & (const struct snd_usb_midi_endpoint_info) { .out_cables = 0x0001, .in_cables = 0x0001 } } }, Regards, Clemens ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA Learn about the latest advances in developing for the BlackBerry® mobile platform with sessions, labs & more.
