[PATCH] USB: usbcore, hub driver enables TT-per-port mode
[USB] hub driver turns on multi-TT mode
This turns on the multi-tt mode in hubs that support it; the Cypress
"TetraHub" products are appearing at retail now, complete with some
of the first Mini-B connectors I've seen shipping.
This will be important for hooking up lots of full speed isochronous
devices (audio, video, etc).
