[PATCH] USB: central handling for host controllers that were reset during suspend/resume
This patch (as515b) adds a routine to usbcore to simplify handling of host controllers that lost power or were reset during suspend/resume. The new core routine marks all the child devices of the root hub as NOTATTACHED and tells khubd to disconnect the device structures as soon as possible.
