[MIDI] Device not found

[Kanazawanaoaki]

I tried to use launchpad_x, nanopad2, and nanokontrol2 devices from 73B2 with #792 launch, but nanopad2 and nanokontrol2 could not find the devices with the following error.

The device can be found by using interactive_midi_config.py to get the device_name of the binary and then using it like Kanazawanaoaki@8d58048.

$ roslaunch midi_controller.launch midi_config:=nanopad2.yaml
