[LAU] ESI Romio II and alsa-midi-latency-test failure

I'm trying to use midi-alsa-latency-test 0.0.3

  https://github.com/koppi/alsa-midi-latency-test/

with an ESI Romio II USB - MIDI interface

  http://www.esi-audio.com/products/romio2/

and it's not working reliably.

The Romio has two MIDI inputs and two MIDI outputs. It is
recognised by my system :

  $ alsa-midi-latency-test -l
   Port    Client name                      Port name
   24:0    RoMIO II                         RoMIO II MIDI 1
   24:1    RoMIO II                         RoMIO II MIDI 2

But no matter what combination I try :

  $ alsa-midi-latency-test -o 24:0 -i 24:0
  $ alsa-midi-latency-test -o 24:0 -i 24:1
  $ alsa-midi-latency-test -o 24:1 -i 24:0
  $ alsa-midi-latency-test -o 24:1 -i 24:1

I get :

  timeout: there seems to be no connection between ports 24:x and 24:x

The transmit LED for the MIDI output lights up once but the
receive LED for the MIDI input never does.

No, it's not a bad connection. Running alsa-midi-latency-test
between one output (or input) of the Romio II and one input (or
output) of another MIDI interface works reliably. What doesn't
work is loopback between the Romio II and itself.

Is this a known problem ?

Thanks in advance.
