The minidump lists USBPORT.SYS as the probable cause. What have you got connected the the USB ports? See if you can update the drivers for them.
MULTIPLE_IRP_COMPLETE_REQUESTS (44)
A driver has requested that an IRP be completed (IoCompleteRequest), but the packet has already been completed. This is a tough bug to find because the easiest case, a driver actually attempted to complete its own packet twice, is generally not what happened.
Rather, two separate drivers each believe that they own the packet, and each attempts to complete it. The first actually works, and the second fails. Tracking down which drivers in the system actually did this is difficult, generally because the trails of the first driver have been covered by the second.
