I'd guess the driver doesn't claim all the interfaces that the device has.

You could add some entries to the snd_usbmidi_port_info array in the driver source ... > Preferably each port would be named after the synth connected to it. Changing port names at runtime isn't supported by the driver. > Then when I play the devices I get messages in /var/log/messages saying > Apr 11 23:03:56 voodochile kernel: [14700.085974] rtc: lost 28 interrupts > Apr 11 23:04:26 voodochile kernel: [14730.054964] rtc: lost 28 interrupts > Apr 11 23:04:56 voodochile kernel: [14760.023963] rtc: lost 28 interrupts > What's up with that? Every thirty seconds, something on your computer eats some CPU and disables all interrupts for about 27 milliseconds.
