FIXES:
 
 - Provides fixes for the following issues:

   - You may not be able to use a USB mouse (or wake the computer with the 
     USB mouse) after suspending or hibernating the computer while continuously 
     moving the USB mouse. 

     NOTE: When this problem occurs, you can still wake the computer with the 
           power button without any loss of functionality. Generally, it is best 
           practice not to move the USB mouse until the computer has completed the 
           suspend or hibernate operation even after this update is applied.

   - The computer automatically restarts instead of resuming from hibernation, 
     or it displays a serious error (STOP 0x000000A in Usbport.sys). 

   - The USB 2.0 controller does not enter the selective suspend mode. Because 
     of this behavior, the processor cannot enter a C3 (Clock-Stopped) power state 
     after you disconnect a device from the USB 2.0 hub that is connected to a USB 
     EHCI controller.
