or just use [r pd]--[print] while playing with the settings dialogs and
copy the messages to resend later...
but i don't know if it will work at all, pd only seems to scan for
soundcards when it starts (which i think is a bug); so you'd have to
start pd with it plugged in, then probably have to switch pd to/from the
non-usb soundcard before/after replugging the usb
i'm not sure if any app behaves nicely when you abruptly unplug hardware
that it is using - there might be a way to handle it in the ALSA plugin
layer, but the ALSA wiki doesn't look promising...
