Usb subsystem is not re-enumerating any inserted device/already inserted device after resume

[Ramesh Chandrasekaran]

Only After merging the Basic suspend/Resume working patch, the following bug can be reproduced.

Insert usb-mouse to board --> Enter suspend --> Enter Resume --> The device which is inserted before, is not re-enumerated/ also it not enumerating any new device inserted at this point.

Also, in normal scenarios(that is without suspend or Resume). Removing an inserted device and then re-inserting back, doesn't work.
