The changing order in which USB busses are detected makes comparison awkward, but these seem to be the only new lines. $ lsusb # with 2.6.25-git Bus 005 Device 001: ID 1d6b:0002 Bus 004 Device 002: ID 046d:c50d Logitech, Inc.

Strange that "Bus 001" is missing in lsusb with 2.6.25 because dmesg does mention it as assigned.
