When the cable is plugged in again, we run the detect code, and figure nothing changed because we kept thinking the cable is there. Therefore no uevent in either case.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
