In rare cases, some devices seem to lose sync and never re-attach on the bus. This seems to happen only when there are more than one device per link, which suggests either an electrical issue, a race condition or a state machine issue. Add two dev_warn() messages to identify the sequence by which the devices become UNATTACHED.
