I does not recover because there is not suspend/resume support. I wrote
almost complete support a lot of time ago which wasn't merged due to two
unsolved issues. The resurrection procedure (actually it is a reinit from
scratch) was very unreliable on my Gina24 for unknown reasons and there
was an atomicity issue in the rawmidi interface.
I can manage to provide you a patch for testing in a few days.
