This patch (as1080) makes a significant change to the way khubd handles port connect-change and enable-change events. Both types of event are now debounced, and the debouncing is carried out _before_ an existing usb_device is unregistered, instead of afterward. This means that drivers will have to deal with longer runs of errors when a device is unplugged, but they are supposed to be prepared for that in any case. The advantage is that when an enable-change occurs (caused for example by electromagnetic interference), the debouncing period will provide time for the cause of the problem to die away. A simple port reset (added in a forthcoming patch) will then allow us to recover from the fault.
