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. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
