USB: root hubs don't lie about their number of TTs
Currently EHCI root hubs enumerate with a bDeviceProtocol code
indicating that they possess a Transaction Translator. However the
vast majority of controllers do not; they rely on a companion
controller to handle full- and low-speed communications. This patch
(as1064) changes the root-hub device descriptor to match the actual
situation.
