the problem is that the "setaddr" tansaction fails. basically, when
you plug something in, usbd notices as it polls the status of the
hub where the port is on. that sets some bits and then we enable
the port, which runs the speed negotiation... and then we do attach.
the device comes up with address 0. then we try to set the address
to something unique (9 in this case) as the bus as *every* device
comes up with address 0 on attach :). that fails, so we give up and
turn the port off again.
i'll try to simulate this issue on my t23, it has uhci controller
as well.
