Hi Felipe, I think I know why my application is not receiving SIGHUP.
When HOST sends SET_CONFIGURATION the set_config() in composite.c calls acm_set_alt(). Now acm_set_alt() calls gserial_connect() and it will create new port. But it never called gserial_disconnect() to close previously called gserial_connect(), so SIGHUP is not generated. But why acm_set_alt() does not do gserial_disconnect() before calling gserial_connect()?
