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?
