 * Midiman Midisport 2x4. This has 2 physical MIDI IN jacks that are read

 * that can be written on endpoints 2 or 4 (at descriptor index 2 or 4,
 * coincidentally) interchangeably: either endpoint will accept a Cable Number
 * field of 0 to 3, and data for a given CN will be routed to the same
 * physical output regardless of the endpoint used for the transfer. But
 * there's a catch: flow-control feedback only goes to endpoint 2 for
 * CN 0 and 2, and only to endpoint 4 for CN 1 and 3. If you send output at
 * high rates for CN 0 or 2 over endpoint 4, or for CN 1 or 3 over endpoint 2,
 * the USB transfers complete as fast as possible, giving you an apparent data
 * rate much higher than MIDI's 3125 cps (easy to measure using dd to blast a
 * bunch of midi data to the rmidi device). Of course that isn't a way to make
 * MIDI faster, just a way to overrun the device buffer and spray bits on the
 * floor. So this device needs the fixed endpoint quirk, the fixed cable number
 * quirk (to make sure CNs 0 and 2 are put on the first endpoint and 1 and 3
 * on the other), and then the fixed mididev-assignment quirk (to match jacks
 * to mididevs so the rmidi devices match the order of the blinkenlights).
