Running status is a feature of the encoding used by MIDI. USB MIDI and the ALSA sequencer use different encodings. A USB MIDI adapter converts from MIDI to the USB MIDI protocol, and the USB MIDI driver converts that data back to MIDI. It is not possible to detect from the result whether the original MIDI data used running status.
