A feature in Windows 8 that speeds up the boot process causes this issue. Windows 8 checks to see if the USB driver communicates with the physical hardware. Because the DLP Endpoint USB driver is a filter driver, it does not communicate with the physical hardware. Windows then changes the load order for the DLP Endpoint driver to System or Automatic, which causes the driver to stop functioning.

NOTE: Windows is using the DLP Endpoint service registry key StartOverride.
