Make Control Endpoint stream transfers more reliable by adding in early aborts for unexpected new SETUP tokens, or unexpected status stage during control stream writes.
Fix corruption in Device RNDIS demos TCP stack when too many connections attempted simultaneously, freezing the device when a page was re-fetched before the first connection was closed.
Fix incorrect model compatibility information in the Host LowLevel demo overview text files.
