To the USB subsystem these devices are plugged in as soon as power is
returned.

I would arrive at the opposite conclusion. Independent from that, loss of
power is not really supported by USB during STR. Obviously it should not
hang, but all devices will be disconnected and reconnected.
But if power is cut with newer kernels and older kernels retain it, something
must have changed. Can you undo the ACPI changes since the last working
kernel?
