3.8.13.3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <jhovold@gmail.com>

commit 5f8e2c07d75967ee49a5da1d21ddf5f50d48cda0 upstream.

The first and second interrupt-in urbs are swapped for some Treo/Kyocera
devices, but the urb context was never updated with the new port.
