If the device is _not_ removable we should not start the event poller as the media will not go away. Having the event poller running will block the open() call as it will try to flush outstanding events, which it can't if the device is in state 'BLOCKED'. So the open() call will be stalled until the device state changed, which might be quite some time depending on the transport.
