And you reverted the previous one I guess.

I'll need to think a bit more about this.

It is possible for the kernel to reset the "Virtual HUB", but then I need a
failsafe test which doesn't cause the looping.

I looks to me like trying to touch any of ports w/o the USB reset is a no-go.

Basically the USB port status is saying there is a device there.

It would be very nice to see some looping debug prints somehow.
