What kind of dongle is this? Maybe you need to get yourself a better one, because a disconnect from the USB is nothing we can really work around. > I notice that flow (and error) control appear on the Todo list, but is > there some way to guard against the whole dongle being taken down? It only protects the host stack and not the dongle. The flow control towards the HCI of the dongle is always used.
