Hi all,

For a AVStream capture USB device, when the user mode application such as
graphedt.exe is playing preview graph, the avstream data is captured and
rendered to the application.

dispatch routine for IRP_MN_SUPRISE_REMOVAL is handled for default PnP
Handler completion of the request and as part of DEVICE_CAPABILITIES's
SurpriseRemovalOK is set to TRUE.

In addition is there any thing to be done as part of AVStream such that the
user application to get aware the device doesn't exist.

Thanks,
