A value of 0 or 1 means that the device driver does not support DMA-remapping. A value of two means that the device driver supports DMA-remapping. If the property is not available, then the policy is not set by the device driver that is, the device driver does not support DMA-remapping.

Check the driver instance for the device you are testing. Some drivers may have varying values depending on the location of the device internal vs. If the peripherals do have class drivers provided by Windows, use these drivers on your systems.
