sorry for the long silence.
I tried what you said and among my other Midi/audio devices (Midi keyboard: Edirol PC-50, Audio Interface: M-Audio Profire 610 and cable Midi to USB: Edirol UM-1Ex), H9 Control recognized one that is called "USB Audio device" and that might stand for the Space, so I connected to it log in and it worked once.
Though it's really unstable and I could never make it happen again since H9 Control shutting down every time I try to connect the Space manually now (it seems to recognize still the Space serial number SP-01617 though…)
