In fact the log shows that the 30-second delay occurs in the middle of
ohci1394 (Firewire) initialization, not USB initialization:

The log at http://lkml.org/lkml/2008/6/6/317 shows two pauses. One in the middle of USB related messages with no FireWire stuff around (17:25:19 to 17:25:44). The other with parport, ieee1394, USB messages around it (17:25:44 to 17:26:31).

From there, the last 17:25:44 message is strange: The device 00110666000013cc which is the controller is reported as being removed. Chris, did you do something at this point?

Also, in http://lkml.org/lkml/2008/6/1/2 you reported a patch which changes the SCSI core's interaction with the driver core as first bad commit. Did you check that going before this commit removes _all_ the pauses, even those around USB or FireWire messages? Or did you only check whether disk drives appear quickly?
