At some time last year, changes were made to the usb drivers to be sensitive to acpi data of some sort (maybe something about hubs, I forget the details). That alone may have been fine on most systems, but then a later update of acpi code started causing problems which in the past might not have affected usb but now does. It's just a vague theory, based on my memory of some change happening last year that injected awareness of acpi data into the usb driver subsystem. I wonder if it would be possible to add some sort of tunable to disable that awareness, if nothing else just to see if it's the cause of any usb trouble. -- Ian
