2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Alan Stern <stern@rowland.harvard.edu>
commit cee6a262550f53a13acfefbc1e3e5ff35c96182c upstream.
This patch (as1460) fixes a regression in the usbip driver caused by the new check for Transaction Translators in USB-2 hubs. The root hub registered by vhci_hcd needs to have the has_tt flag set, because it can connect to low- and full-speed devices as well as high-speed devices.
