No way to detect closed port (ALSA?)

[thebne]

First of all, thank you for the great package. I'm using it through mido.

It seems like I can't get notified once the port is closed (physically - the piano turned off, the USB is unplugged etc.).
It's important because once it reconnects I don't see any new events until I reinitialize the port.

It might be an ALSA problem - I'm running with ALSA and Ubuntu 18.04.
Tried using set_error_callback() and checking is_port_open(), didn't seem to change much.
I wouldn't mind polling/running select() on the USB port. I just don't find a reference to any fp I could use.

Any help here? :)

I investigated further and realized it's an ALSA problem :( nevermind, thank you!
