Actually I was wondering if you plan to support plugging in multiple NetChip UDC cards, but I can't imagine it would be all that useful. At this stage g_midi only support one MIDI in jack and one MIDI out jack, because that's all I need for now. In order to support more than that one would need to add more jack descriptors and corresponding rawmidi substreams, none of which should be too tough. But I think it would make the most sense for all that to still appear under the one ALSA "card", with a single index and id as Clemens suggested, at least as I understand it. - Ben.
