HDK865 also has a couple Type A ports, I am using them with devices already plugged in during boot and I haven't hit a problem like that, but I think I've seen the same issue when hotplugging. IIRC the behavior was a bit weird, like plugging a device in the Type A port (USB1) nothing would happen, but unplugging/replugging the type C port (USB0) would cause the Type A port device to start working..
Have you tried with the devices already plugged in before booting?
