When Alan's patch is applied, your version of lsusb does show the USB roothub and the high speed hub, unlike the version of lsusb I have (version 0.82). With Alan's patch reverted, the output from your lsusb is the same as with the patch (except for reordering of the EHCI/UHCI bus). > > Why are there lots of nulls?
