Subject[patch 20/38] USB: fix regression in usbip by setting has_tt flag
2.6.38-stable review patch.  If anyone has any objections, please let us know.


From: Alan Stern <>

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
