 The last I heard about any of this stuff your problems were related to
 usb xfer stalls.  If this no longer true then please provide me with a
 recipe for recreating the issue.  If it's a driver/net80211 issue I will
 try to fix it.  If it's in the usb subsystem it's unlikely I'm going to
 pursue it.
 
 FWIW the "new usb stack" is unlikely to help you.  The author broke ural
 in porting it and so far as I know it's not been fixed.  This is
 independent of whether or not any changes in his code base will resolve
 the original issue.
